@cavaliertusky I implemented a router on my server. You only need a motherboard with two ethernet interfaces and you can route (and firewall) using Shorewall. My implementation uses Arch Linux for the OS.

@cavaliertusky I'm running #OpenWRT on my VDSL router with vectoring at home. Hardware is a BT Homehub 5.0 Type A. Works perfectly fine, with all the usual advantages of having full control over the open-source software you're running, etc.

@cavaliertusky
I've worked a lot with OpenWRT. Can't say a word against it, getting a supported router and flashing it is the easiest way to go.

There is a great project called Turris, who do open hardware routers with an upstream-following OpenWRT fork. Check it out :)
