Running Wireguard on a switch

Running Wireguard on a switch

Hi,

Nowadays, manageable switches often run Linux.  Ben Cox managed to run
wireguard on such a switch from Dell: https://blog.benjojo.co.uk/post/dell-switch-hacking

He's not talking about performance (that was not the goal): the CPU on
this switch looks like a low-end ARM so it's probably not that good, but
it's still fun :)

Cisco datacenter switches like the Nexus n3k have a x86 CPU and run
CentOS, so I wonder if somebody already tried Wireguard on those?

Hi Baptiste,

the problem with switches is often that they have closed-source drivers
for hardware NAT etc. Thus it's not really that funny to hack them.
If every driver they use is FOSS, you could easily add OpenWrt support for it and
then everything is update-proof. Until then I rather hook an Intel NUC
or a router with IPQ401x processor to the switch for doing WireGuard.

Regards,

Vincent Wiemann
