OpenWRT has WireGuard support, so also, every router you can put an OpenWRT image on.

EDIT: I'm using it on my Netgear WNDR3800, and my grandmother's Sitecom WLR-4000 (which is a rebranded Sitecom WL-351, which is a rebranded EnGenius ESR9850).

You can run it on Ubiquiti's EdgeRouters: https://community.ubnt.com/t5/EdgeRouter/Release-WireGuard-f...

And if you're feeling like a fun weekend hacking project it's also available on OpenBSD which runs on the EdgeRouter including support for the onboard packet accelerator.

Nothing against vyatta/edgeos but since getting into edge cases requires command line anyway, you can just start there without too much trouble.

You just get to port Go to octeons during that weekend then. But if you do, I will be happy! \o/

To be fair, then your bandwidth penalty just comes from something else.

(I run a large number of ERs, mostly because you can easily run so much other software on the hardware -- but they're not great devices if you need performance or reliability. "You get what you pay for" absolutely applies.)

Omnia Turris runs it fine.
