Bridge mode vs

Bridge Mode vs. Router Mode: Understanding the Difference

In the realm of networking, the choice between bridge mode and router mode can significantly impact the performance and functionality of your network setup. Both modes serve distinct purposes and are employed in different scenarios, so understanding their differences is crucial for optimizing your network infrastructure.

Firstly, let's delve into bridge mode. When a device, such as a modem or router, is set to bridge mode, it essentially functions as a bridge or pass-through device, allowing another device, typically a router, to handle the network routing tasks. In this mode, the bridging device doesn't perform any routing functions and simply forwards data packets between the connected devices without modification. Bridge mode is often used in scenarios where a separate router is desired to manage the network traffic and provide advanced features such as firewall protection, QoS (Quality of Service), and VPN (Virtual Private Network) capabilities.

On the other hand, router mode involves the device performing both bridging and routing functions. In router mode, the device not only forwards data packets between devices on the same network but also manages the routing of data packets between different networks, such as the local network and the internet. Routers in this mode typically offer features like NAT (Network Address Translation), DHCP (Dynamic Host Configuration Protocol) server functionality, port forwarding, and more, making them suitable for standalone network setups where all-in-one functionality is desired.

In summary, the choice between bridge mode and router mode depends on your specific networking requirements. Bridge mode is ideal when you need a separate router to manage network traffic and provide advanced features, while router mode is suitable for standalone setups where a single device handles both bridging and routing functions. Understanding the differences between these modes empowers you to make informed decisions when configuring your network infrastructure.

Trusted Firewall Solutions

I never advertise software that I have not personally used. With that being said, I have put together a small list of firewall software that I recommend with descriptions and usability.

pfsense: One of the most extensive and configurable open source firewalls out there. Based on FreeBSD, this software is loaded with everything! One of my favorite features is the easy to use certificate based VPN tunnel. Overall, the learning curve is difficult but once you have it down, you'll feel like a network pro.

SmoothWall Express: Based on Linux this firewall has an easy to moderate learning curve with some possible hiccups during installation depending on the hardware you use. Overall I have the most experience with this one and it works great out of the box for business and home users looking to protect their network.

IPFire: This Linux based solution is new to me but so far I have no bad things to say. The learning curve is on the easy side and I recommend this for users that want to setup a firewall own their own. With all of the usual features as other firewalls the VPN configuration is easy to setup as well as most of the features.

A Note On VPN’s: I make mention of VPN’s a few different times here for a reason. As a systems admin I have had more than one call from employees that could not connect from a remote location and it’s a big deal for me to find a solution that works no matter where your users are in the world. Some of the older versions of Smoothwall were damn near impossible to configure correctly for multiple users at different locations and in the end I migrated over to pfsense. Also; I made no real mention of security in this article for a reason. If it was not secure I would not recommend it. But to be realistic and firewall can be configured as secure as you want. My top picks have a good track record for security, updates and functionality but I also encourage you to do your own research before making a commitment to any solution that protects your data.

Supermicro SuperServer E302-9D Review: A Fanless 10G pfSense Powerhouse

Intel launched the Xeon D-2100 SoCs in early 2018, with a feature set making them a fit for several verticals including edge servers, networking, and storage. One of the key advancements made in the Xeon D-2100 compared to the first-generation Xeon D-1500 series was the inbuilt support for two additional 10G network interfaces. With TDPs starting at 60W, the Xeon D-2100 SoCs lends itself to some interesting and unique server and edge procesing products. One such system is Supermicro's passively-cooled SuperServer E302-9D sporting the Xeon D-2123IT SoC.

As part of the evaluation efforts of different technologies and products, AnandTech editors are regularly tasked with the building or identification of suitable testbed systems. The requirements for these systems often mirror the requirements of software developers and homelab enthusiasts. The increasing adoption of 10G across various networking / network-attached storage product lines meant that we were on the lookout for a low-power system with multiple 10G ports to act as testbeds. We reached out to Supermicro after spotting their X11SDV-4C-TP8F-01 FlexATX board. Supermicro graciously agreed to loan us two SuperServers based on the board to take for a testdrive - the E302-9D in a passively-cooled desktop form factor (that we are taking a detailed look at today), and the 5019D-4C-FN8TP 1U rackmount version.

Introduction

Intel's Xeon D product line targets servers used in power- and size-constrained scenarios (including edge compute). This includes applications across multiple domains such as storage, networking, and communication. The product line integrates server-class CPU cores along with the platform controller hub (PCH) in a single package. The first-generation Xeon D (1500 series) was based on Broadwell-DE cores along with the C220 server PCH. Our launch coverage of the Xeon D-2100 series brought out the details of the updated server core (Skylake-DE) and PCH (Lewisburg C600-series). The relatively power-hungry PCH update and the addition of AVX512 capabilities in the Skylake cores meant that the minimum TDP went up from 20W in the D-1500 family to 60W in the D-2100. However, the updates also brought in welcome connectivity updates.

The Supermicro SuperServer E302-9D / X11SDV-4C-TP8F-01 we are looking at in this review utilizes the Xeon D-2123IT with a 4C/8T configuration. It has the least TDP of all members in the D-2100 family, yet comes with support for up to four 10G ports. The 60W TDP of the SoC allows Supermicro to utilize it in a passively-cooled system. To the best of our knowledge, this is the only off-the-shelf x86 system that provides consumers with four 10G Ethernet ports in a fanless configuration.

The Xeon D-2100 series offers support for up to 20 PCIe 3.0 lanes, 14 SATA 3.0 lanes, and 4 USB 3.0 ports. The D-2123IT can be equipped with up to 256GB of DDR-2400 ECC memory. In creating the X11SDV-4C-TP8F-01 board used in the E302-9D, Supermicro has worked around these features to create a compact board / system that appeals to developers and home-lab enthusiasts working on cutting-edge networking applications.

The SuperServer E302-9D is marketed as an embedded system comprising of the CSE-E302iL chassis and the X11SDV-4C-TP8F-01 board. The power supply is an external 150W adapter. The chassis sports a power button and status LED in the front panel, with all the I/O ports in the rear. The chassis supports a low-profile PCIe card mounted horizontally. The dimensions come in a 205mm x 295.2mm x 73mm. The gallery below takes us around the external design of the system.

In the rest of this review, we first look at the detailed specifications of the board along with a look at the internals of the system. This is followed by some of our setup and usage impressions. In particular, we look at pfSense installation on the system along with some basic benchmarks. Finally, we take a look at the power consumption and temperature profiles before offering some concluding remarks.

I get asked/see far too many questions, far too often, about things that are very Google’able or have already been discussed 10,000 times here,so here is a definitive ‘switch 101 by Muffin’ to help some of you on your way into the world of switching (and routeing) with switches.Before we begin, if you don’t know what a VLAN is and want to know, please read my blog post before continuing this.Previous 'Let's talk about':Let's Talk About PfSense, Physical Or Virtual?Cakes have layers, not switches …right?Now, without digging too deep into this, we are looking at layer 2 and layer 3 of the OSI model. If this is a new term to you, or you’re not exactly sure what it is, then I implore you to do some reading on it as it is paramount to understanding the basics of networking. However, to keep things short and sweet for this post, this is what is meant by layer 2 & layer 3 when looking at switches:Layer 2: This will only deal with switching. Meaning MAC addresses will be used to move packets between ports.Layer 3: Layer 3 switches will do the above, but they also have the ability to route packets based on IP addresses, this means that machines in different networks//VLANs can communicate with each other via the switch, since it can act as a gateway for these networks. This is additional functionality and does not mean it works differently to a L2 switch.What do you mean my switch can route?You have 2 machines in 2 different VLANs, machine A and machine B in VLAN 1 and 2 respectively. You need to transfer files from machine A to machine B, how does this happen? Routeing.Routeing must take place when communication across networks is required. This is why your router is called a router, it is routeing your local traffic to the internet. The same thing happens in the above scenario, something has to route this connection, this will be your default gateway. Machine A will know machine B is not in its local network so will send the request to its default gateway, this is where L3 routeing will take place.Normally, this is your router, whether it be a shitty off the shelf box with 50 bazillion antennas, or something better like pfSense//Sophos UTM, however, this doesn’t need to be the case. Layer 3 switches have the ability to be assigned Switch Virtual Interfaces (SVIs). What this essentially is, is a default gateway for a network, that lives on the switch, this allows the switch itself to route packets between networks, without the need for an actual router.The benefits of L3 routeing on a switch is speed. Whilst routeing in software is just fine for most applications, high-end switches can route at speeds that traditional routers simply cannot handle without getting into insane costs. If you had a 10Gb network, for example, and wanted to route at 10Gb, you’d be looking at doing this on a L3 switch.Okay, what kind of switches should I be looking at?There are 3-4 main marketing terms used to describe a switches capability, and I’ll go through these:Unmanaged Switch: These are dumb switches that operate at L2. You plug shit in, it switches based on MAC address. That’s it. No VLANs, No QoS, No fancy routeing, No ACLs. This is one step above using a hub which no one ever should be using now. If you’re looking at an unmanaged switch for the core of your homelab I would highly recommend against this as there is no progression to be made. Unmanaged switches work well as access switches, that is to say connecting dumb devices that can be on the same VLAN.Managed Switch: These are the kinds of switches you should be looking at. These can be either L2 or L3, it really depends on the manufacturer, usually, they’ll be a L3 version and a L2 version. Managed switches allow for configuration hence, managed. Managed switches will support VLANs and any number of additional features depending on the switch.Smart Switch: These switches normally are an in-between between an unmanaged switch and a managed one. Usually having minimal management options and supporting some form of VLAN implementation but not normally all the features that your traditional managed switch will. I say normally because these terms are all marketing terms, there is nowhere that these are defined as a standard.So, 99.9% of homelabbers, in my opinion, should be looking at getting a managed switch, or at very least a smart switch.What do you mean by ‘management?’Management is how you will be configuring your switch. This can be via a number of ways including:CLI via consoleTelnetSSHWeb GUICLI via console is the main way to use switches, once you’re console’d in you can then assign an IP address to your switch and manage it via telnet/SSH. Console cables are called rollover cables and they look like Ethernet cables, but they are not. These kinds of serial cables are slowly disappearing from switches but for the most part, if dealing with enterprise switches, you will encounter this. Rollover cables can be found for cheap, what is rare these days is having a machine with a serial connector, which is why you’ll buy one of these bad boys, look on Amazon to find one compatible with your OS and not a pile of shit.CLI’s will also vary across vendors, but for the most part are all variations of Cisco’s IOS. Configuring devices via CLI can be daunting for some, but I promise you there is no alternative. If you want to learn networking and are serious about getting to grips with enterprise grade equipment then you will need to get your feet wet in some CLI, there is no skirting around this. Cisco CLI is extremely documented so please don’t let this get you, doing basic things with your switch via CLI really shouldn’t take you long if you spend a bit of time doing some reading.Web GUIs. Web GUIs are …interesting. They range from okay to holy Jesus why. A lot of the cheaper smart/managed switches will only offer a web GUI with no option for CLI. Sometimes, this is okay. If you just want to get to grips with VLANs without learning any CLI, then this solution might be fine. Personally, I’m a CLI or die kind of man. You should be aware that switches that offer both a fully featured CLI and web GUI normally only allow basic functions to be configured via the GUI.What kind of ports am I looking for?So you know switches use Ethernet, but what’s going on with this SFP stuff?SFP stands for small form-factor pluggable. SFP modules look something like this or like this. An SFP port essentially allows the port to be converted to whatever is on the end of the SFP, this is usually fibre.You may also see SFP+, this is an upgraded spec of SFP that supports 10Gb. When you’re looking for 10Gb switches these are the kinds of ports you will see 90% of the time. SFP+ is backwards compatible with normal SFP transceivers, so you can still do 1Gb if required.SFPs are weird, and by that I mean vendors are assholes. On some switches, vendors will lock the vendor of SFP that can be used in their switches, making you buy their insanely priced receivers. Never assume any old SFP will work in your switch, sometimes this is the case but unless you’ve read this is the case, don’t assume so. Read your potential switches documentation to see what SFPs the switch supports, and try and see if anyone has had luck with other brands. You have some options as to SFPs though:eBay normally has official, used SFPs for very cheap.Buy cheap compatible receivers from fs.com (I can highly recommend.)Buy DAC (Direct Attach Copper) cables. These are solid copper cables with the SFPs built into each end of the cable like this. SFP ports will act just as regular ports, it’s all the same thing as a normal port you’re just given the option to use a different medium.Some switches share the SFP ports with the regular ports, so instead of, for example. 24 Ethernet ports and 2x SFP ports, the SFP ports are shared with ports 23 and 24, so you either use Ethernet or SFP. Make sure to check your switches config if you have SFP ports. A 24 port switch with SFP slots not shared with the Ethernet ports will be a 26 port switch, for example, which is why you may sometimes see 52 port switches, 48 ports for Ethernet, 4 for SFP.Some switches will also have the following:Console port: As described above this is for management as is not a normal Ethernet port.AUX port: Again, this is not a normal Ethernet port but is used for management under some deployments.Stacking port: This is used to stack multiple switches together to act as one switch, this can sometimes be a HDMI port.Speed/Duplex/MDIX.You want a gigabit switch at minimum. Seriously, don’t bother with 10/100 switches. 10/100 is described as ‘fast Ethernet’ and a lot of stuff on the market will be for these kinds of switches. A lot of eBay searches will bring these switches up even when searching for Gigabit switches because a lot of FE switches have 1/2 Gigabit ports on them, normally used to uplink to another switch.Always make sure all ports of your switch are Gigabit. Make sure to grab the spec sheet of any potential buys to ensure that all the ports are Gigabit and not a fraction of them.Duplex refers to how the switch can send/receive data. Half duplex means the switch can only send or receive at any given time, full duplex is send and receive at the same time. All switches in the past 10-15 years will do full duplex, but most give the option to run at half duplex speeds for legacy devices.Auto MDIX is also something that almost every switch has nowadays but it is worth mentioning. In the days before Auto MDIX, to connect two switches together you would need to use a crossover cable so that the receive end of one switch would be on the transmit* end of the other allowing communication. Auto MDIX allows the switch to detect the required connection type and change this on the fly, negating the need for crossover cables.Stacking.Switch stacking is a very cool feature that high-end switches employ.Switch stacking allows you to, essentially, 'combine' two of the same switch into one logical switch. This can be awesome for splitting connections across switches for redundancy. Lost a switch? No problem!Stacking utilises special 'stack ports' that have high bandwidth capacity to transfer data between the switches, these are vendor specific.Whilst switch stacking is cool, it does require you to have 2 switches which can be an unnecessary overhead to a lot of labbers.PoE.If you need/want PoE switches become a lot more expensive. If you need PoE and Gigabit then prices can skyrocket depending on how many PoE ports are required. There are 4 types of PoE currently, only 2 of which will matter in 99.9% of homelab deployments.IEEE 802.3af – 15.4w powerIEEE 802.3at – 30w powerIEEE 802.3bt – 60wIEEE 802.3bt – High Power, 100wYou’re almost always going to be working with 802.3af/at, so you can ignore the other 2.As well as the different PoE standards there is also active and passive PoE. Devices that have the 802.3af/at standard will be active PoE, this means that the devices talk to each other to ensure the correct power requirements are met.Passive PoE has no handshake, plugging in a passive PoE device into a switch that is providing the wrong voltage can fuck up your device/switch, so ensure voltages are correct when using passive PoE.Power ConsumptionPower consumption can range from "hey this isn't so bad" to "jesus fuck was there supposed to be a nuclear reactor with this?".Power can vary a lot based on the type of cooling the switch utilises, amount of ports, PoE etc. Whenever you're looking for a switch I would recommend looking at the manufacturer's spec to see how much power the switch has been rated for. Manufacturers will always put this information in the detailed spec of the switch.More enterprise switches will also have dual PSUs however this isn't necessary in most homelab environments so I wouldn't worry about it too much.Soo... What switch should I get?This is the question. Recommendations will always be different based on your needs and what is available in your region, but here are my picks for those of you looking for a switch. Again, this is my personal opinion on what would fit the needs of the many, not a definitive list.HP 1810G-24GPros:L2 managedSilent, no fanWeb GUI is decent enough, I've used much, much worseLifetime warrantyMax power rating: 30wCons:No CLI by defaultNo dynamic LAGGsWeb GUI can be far too 'clicky' to do basic things2x SFP slots share p23/p24 with ethernetHP 1910-24GPros:L3 managedSilent, no fanWeb GUI is decent enough, I've used much, much worseLifetime warrantyHas CLI kindaMax power rating: 60wPoE variantsCons:No dynamic LAGGsWeb GUI can be far too 'clicky' to do basic thingsCLI is pretty basicMikrotik CSS326-24G-2S+RMPros:L2 ManagedSilent, no fanWeb GUI is okayMax power rating: 19wHas 2x SFP+ PortsCons:Feels lighter than a featherSwOS can be ...interestingBlinkies don't actually blink like you'd expect a switch toNo CLICisco 3750EPros:Full blown L3 switch with all the bells and whistles2x 10Gb via Cisco X2 moduleCisco IOSPoE variantsCan stackCons:Can be loud(ish)Max power rating: 256-1150wFirmware locked behind paywall, but still very obtainable.Cisco 3560E is the same as the above without stacking so is also very much worth a lookDell 5524PPros:Full blown L3 switch with all the bells and whistles2x 10Gb via SFP+GUI & fully featured CLIMax power rating: 30wPoE VariantsStackableLifetime warrantyCons:Can be loudI've probably forgotten some things and will add these in as I'm reminded.I hope this has helped at least some of you out there.~~Muffin via /r/homelab

Next challenges for the firewall technologies and for their administrators

The functionality of firewalls tries to find the right balance between the required security and the required service providing from the beginning. Earlier, firewalls just hid the internal network from the ‘dangerous’ Internet, but now firewalls deploy applications, make authentication and authorization, discover and prevent attacks, threats and malicious contents. Functionality changes have followed the possible implementing places of firewalls. From the borderline, firewalls have conquested new places inside the internal network between desktop and server networks, defending the most important data inside internal networks and adding extra services as a (HA) load balancer and so on.

Firewall vendors have been trying to fulfill new requirements and sometimes spend a lot of money on unrequested and usefulness things. As the complexity has grown up, management interfaces look like a mixed dashboard of the ISS and Wanamaker-organ together.

Challenges of the past

In the ‘stone age,’ the network was simple: the net had consisted of two parts: internal and external sides and in the middle there had been the firewall.

The appearance of the DMZ just divided the server network into internal and demilitarized zones, from viewpoints of the desktops.

The next step was when firewalls defended the server farm from malicious desktops. The functionality of the firewalls has been extended with ids/ips services.

Nowadays firewalls can run as VPN gateway, ids/ips, load balancer, web filter, content filter, virus scanner, client authenticator, router, application publisher and so on. However, integration with NAC systems or the radius based 8021x authentication systems cannot be seen as easy, if it is possible at all.

-------------------------------------------------------------

Solutions to tasks required by new technologies are as follows

In clouds and in DC’s:

From the viewpoint of the server infrastructure, new IT models like DevOps, cloud solutions create some new challenges and requests, as the quantity of servers and the requested connectivity could change in every minute.

In this case, the connectivity of servers does not need more sophisticated rulesets, as masses of servers work in the same configuration and have the same functionality. The connectivity is simple, as it contains just some ports and protocols. The external service level access does not often require special things: all servers are clones of a well-configured server, and if something goes wrong, it is better to destroy all affected clones and re-generate them based on the fixed one.

SDN without virtualized firewall solutions doesn't exist, but the functionality of the firewall doesn’t require all-inclusive services in the firewalls on their layer3 points which control the traffic between different parts of the clouds: access control for the other server connectivity and dynamical routing functionality probably are enough; in addition load balancing could also be option.

In a well-planned software structure, direct access from desktops is not necessary.

An interesting method could be when some kind of servers are configurated without default route. All requested connectivity should be well known before the creation of servers in cloud and just some static route should be enough for the connectivity. In this case, servers will be unavailable from other nodes and for the attackers, as well.

Desktops:

BYOD, homeworking and new threats of ransomware increase the requested firewall functionality and tasks too, from a desktop side. Integration with NAC and the 8021x solutions will also create challenges for admins and for firewalls. The Kerberos or radius based centralized authorization solutions can improve the security. If infrastructure is able to support these solutions from workplace switches to servers, security will be raised. Automatic policy deploying into security points is required, as well.

It could be an alternative way - provided that the structure is declared to this - if all desktop clients run as a homeworking desktop and it does not really matter, where they are. The entry points between the desktop environments and the server environments are similar. All desktops from all places are connecting through a centralized application deploying service. In this case, entry points need more powerful machines. Implementing phases of this functionality into employees’ culture may not be too easy, however, because if implementation of this functionality does not contain more advantages and new user experiences, they will just see it as a new obstacle in their work.

Nowadays, employees prefer to see the same functionality on their desk, regardless of where it actually is: at home or in the office building. Contrarily, a lot of well-known functions are very dangerous and outworn, as file server services, dblink based applications and so on.

IMHO, I would try to cut back file server functionality and file-based workflows, because when an employee makes a copy of a document into desktop (forking of the contents), this document could leave the defended infrastructure and this could be a possible leaking point. In addition, the back copy procedure may open the infrastructure for dangerous contents.

Firewalls can report the copying procedure, handle viruses, however new threats could be faster than the update.

Nowadays, Sharepoint-based solutions can handle these requests. If advantages of Sharepoint (or different SharePoint-like solutions) contain more comfortable features than simple file server solutions, the migration/implementation will be easier. The reason is that all users are conservative when changes affect their working-tools.

Ransomware's attack throughout file server functionality, as well. Forking of contents demands more human resources if somebody wants to merge different versions of documents. And this is the point where shared Documentum functionality can overtake file servers. Prerequisites are just Internet connection and well-configured access services.

Different ways

Leading firewall vendors have recognized these changes and they usually have two different ways to reply:

Lightweight, but fast configuration capabilities and functionality inside clouds without appliances on the layer-3 endpoints, uniting the routing and firewall functions. This is the way for the software-defined networks. In this point, automatic configuration is more important than the available, but unused firewall services

Improved functionality and integration on the borders with different security systems (NAC, Radius, Kerberos, LDAP, AD, etc.) on firewalls that are between the desktops, internet, and server farms. Here, sophisticated configurations and collaborations with other systems are more important.

Automated API based configuration of the firewall is required in both cases, and another important aspect is that in the first case, integration can be done with different cloud management platforms like ansible or puppets. In the second case, the collaboration with the other systems is strongly required.

Actually, I am waiting for an integrator solution which is similar to the Oracle Fusion for servers and middlewares. I think this could hide different syntaxes of the API and make integration with other systems easier.

My view is that in the near future firewall admins have two different ways to follow: transforming themselves into ticketing machines and trying to follow waves of daily requests or improving their programming abilities for automated configurations.
