I basically just followed the OpenBSD documentation! One of the big advantages of OpenBSD is that pretty much everything you need to know is contained in the manpages. As I'd said above, we ended up using RFC 3378 EtherIP to link the two layer 2 broadcast domains across the Wireguard tunnel. OpenBSD supports this with the etherip interface. You end up creating a bridge with the etherip interface and whatever physical Ethernet interfaces you want to bridge, on either side of the Wireguard tunnel. I also tried VXLAN but did not have good results. I'm not entirely sure it wasn't a problem with my configuration. Traffic often went one-directional, where broadcast packets from Site A made it to Site B, but they did not come from Site B to Site A. EtherIP worked right off, so I didn't investigate further. |
