On the [remote2] router, all of the wired connections are on the 10.1.1.0/24 network and broadcast works which is what I need.

Yeah, I have the advanced setup instructions in front of me. However, that appears to be the bridge on the same 2 machines where the WG client & server live. I think I'll just try it and see what happens
