@prologic@twtxt.net I find the L2 mode where you have one interface and multiple hosts to be tricky. Its best if you are trying to make a full mesh style. But then all hosts need to be able to see one another.

I have had more success using point-to-point connections where there are only two ends to each interface. It means you have a ton of interfaces and udp ports. but you can share the host IP across the interfaces. Add to that a simple router proto ala OSPF or RIP and you can navigate around not having a full meshnet.

I have dozens of localnet wireguard connections and many more connections to others that use bgp for route propagation.
