I agree on principal, but I often find that the GUI abstractions don't always map to the linux tooling/terminology/concepts, which often ends with a head bashing against the wall thinking "this is linux, I know it can do it, and I can do it by hand, but what is this GUI trying to conceptualize?!?!"

I was recently introduced to a Barracuda router, and bashed my head against the wall long enough to discover it had an ssh interface, and linux userland, and was able to solve my immediate problem by directly entering the commands to get it to [temporarily] do what I needed. (Of course, using the GUI to reapply settings wiped my manual configuration...)

I've used pfsense, OpenWRT, Barracuda, Verizon's OEM router (Actiontec) and they all represent the same functionality wildly differently.

Worth noting that pfSense (and OPNsense) are not Linux-based, they're based on BSD, specifically FreeBSD. While it's possible to have standard router OS web UIs that are cross platform, the underlying technology is different, so it's not really a surprise that there will be differences in how the devices running these OSes are configured.

Not much different. FreeBSD's pf is a port of OpenBSD's pf, and nftables are heavily influenced by them.

At this point I rather doubt the sanity of people still sticking to iptables tbh.

So there is approximately one concept of "packet filter done right". UI madness is on UI authors.

The primary reason I stick to iptables instead of nft is that I already learned iptables decades ago, and some software I interact with still defaults to iptables and/or does not have full support for nft.

Why do you doubt the sanity of people sticking to iptables? What makes nft compelling?

My main reason is that nft applies configs atomically. It also has very good tracing/debugging features for figuring out how and why things aren't working as expected.

That said, I think many distros are shipping `iptables` as the wrapper/compatibility layer over nft now anyways.

as somebody that's not a network engineer by day and has barely grokked iptables, could you recommend some resources for learning nftables ?

There is iptables-nft, which is iptables with an NFT backend.

Are they? I recently had to learn nftables and they seem to be iptables but with a slightly nicer syntax and without pre-defined chains. But otherwise, nftables directly maps to iptables and neither of them seem similar to pf.

I had a similar experience with FreeNAS (now called TrueNAS): I'm sure it's great for some people, but I ended up fighting the abstraction layer way more than I benefited from it. I personally found it easier to just run Samba on plain FreeBSD/OpenZFS.

I guess I'm different. I typically want my router/firewall/network services box to Just Work. I've made a career in deep-in-the-weeds system administration and engineering. Having to hunt down man pages, examples, tutorials, etc for the dozen or so fiddly bits make up a modern Linux- (or BSD-) based router was fun the first time, not so much the 10th. Been there, done that, got the t-shirt.

I will concede that the OpnSense UI is far from perfect. I would really like to see a device-centric view that lets me set all the things related to that device from one screen (or possibly one screen with multiple tabs). For example, if I add a Roku device to my network, I want to enter in the MAC address and then be taken to a screen where it will let me set the hostname, pick a static IP address, hand it a specific DNS resolver IP, see all of the traffic going to/from the device, only allow it access to the Internet between during certain hours, etc. All of this currently requires jumping around between multiple disconnected parts of the OpnSense UI.

I feel almost exactly the same as you on the subject. When I was young and starry eyed I built my own router out of a PC running openBSD, all by hand. Nice learning experience, interesting OS, but definitely not maintenance free especially around system updates as back then openBSD packages and sys upgrades required recompiling everything. Now I do the same mini-PC thing as the OP's article but I just put OpnSense on it. Agree the UI can be maddening at times but the thing is rock solid, and has very polished update and upgrade mechanisms. Built-ins/plugins are great - unbound, wireguard, openvpn suricata, backups to git etc. Also I like that it is BSD based, my network experience was learned on Cisco's and Junipers in an ISP setting and Linux networking has always driven me crazy

I've been running OpenBSD as a router for almost 20 years I think? These days, the only ongoing maintenance it requires of me is running `syspatch` and `pkg_add -u` periodically to keep things up-to-date, and then `sysupgrade` when a new release comes around. It's way more hassle-free than in the old days.

I'm at a stage where I don't want to be doing network management on my weekends. I have a Ubiquiti router that's pretty good, and for my router I'd like something like TrueNAS for my NAS, a distribution that completely turns the hardware into an appliance I can configure once and forget about.

Is there something like that?

Pfsense/opnsense would be one option (based on FreeBSD). For Linux there is OpenWRT, which you can either run as an alternative firmware on quite a few consumer routers/access points, or install on a PC or Pi or similar.

Caveat: I have only used OpenWRT on a high end consumer router (GL.inet MT6000) out of those. That works well, anything else is based on reading about people using those options.

For all of those, once you set it up you don't really need to do much except install updates a couple of times per year, or if you want to forward a new port or such.

Nice, thanks! I had an OpenWRT router back in the day, but it had no Web interface. I'll try OPNsense, thanks.

OpenWRT has the LuCI web interface you can add to it (often included in installs) which lets you do pretty much everything.

I recently dumped opnsense because they took a stand against a few things I was trying to do (ex, webUI on wan port IIRC) which make sense at a high level. But I _HATE_ devices that think they know better than me. I was trying to configure it on a _LAN_ such that the identified WAN side was actually my local lan, and I spent an hour hacking it to work and was like "you know if they can't get this shit right i'm out". There are a lot of places in the technology world where someone who thinks they understand my use case makes a decision based on some narrow world view because they can't understand that not everyone trying to use their product is some idiot home user using it for their home network.

Yep, this is the way. You will learn loads using Linux but this is not something you want to go wrong.

I used a lower power Intel Atom mini PC with an additional NIC as a router for years. I tested it and found it could route around 300Mb/s which was plenty.

But then I got gigabit internet. So I bought an Intel 4 port GigE card from eBay and now run OPNSense as a VM. If you get the right Intel card you can pass through ports to VM individually, which is nice for playing (don't know the exact details but look for cards with virtualisation support, mine is an 82575GB I think).

To be fair, my setup still probably has too much to go wrong, due to the VM thing, but I just haven't got round to getting dedicated hardware, and it's worked fine for a couple of years now.
