alt Hacker News> How about OPNSense on open hardware of your choice
Yes, it's a possibility, but if you want to tinker, I think a plain Linux distro like Debian is better. Turning it into a router is literally a couple of kernel parameters and a few iptables rules to set up NAT. Nowadays that's less than fives minutes of work with Claude.
This buys you much better performance and hardware compatibility relative to a BSD system, as well as lower resource usage and attack surface (no GUI or other unnecessary additions). WiFi support on BSD is bad, but on Linux you can use hostapd and almost immediately get an access point for free. And of course Linux is also better if you intend to run other stuff on the same hardware.

Thats more or less what I did, and nix just made sense for the job. For 99% of people I'd say no its not worth it to tinker, just go with opnsense virtualized so you get at least some the benefits of the better linux drivers. By that I mean NBASE-T on various intel chips and while intel's igb is fairly solid on unixes many other vendors' drivers are less so. However if you're willing to figure out configuring per your needs you definitely can get a lower latency router with all the same capabilities and more, with it's components more sanely isolated via containers.
Please support your claim about (networking) performance of BSD-based systems and Linux with some source(s). It surprised me. Thank you.
Some people want a webinterface tho.
But what if you don't want to tinker? I switched to OPNsense as a direct replacement for our Asus "WiFi routers", and it has been phenomenal, reliable, and does everything needed - when you just want it to work, it really just does. But when you want more advanced functions, there are tons of plugins and stuff that you can run natively, while still having a true CLI.
I suppose it comes down to what you said - "if you intend to run other stuff on the same hardware." Is it a good idea to run all sorts of extra stuff on your literal firewall/router? And if you did, I'd assume using a hypervisor is safer anyway? That way you can have the GUI and reliability of OPNsense but have a Linux distro beside it.
You also said that Linux has much better performance vs BSD, which seems rather far fetched. Got any data for that?
One other thing: OPNsense comes with a ton of helpful rules to eliminate bot traffic, allow IPv6, different NATs, VLANS, etc which you'd have to add manually. Not the end of the world, but worth considering.
