Let's say I have this setup: VPS A for Netmaker, Server B and C under the same LAN with firewall and I can't port forward any of them (incl UPnP) I was able to setup netmaker on A, connect B and C to a new created network, setting up a new additional node on A (call it A1). However, while I can ping A1-B and A1-C, I cannot ping B-C. Can someone help?

this will be easier to do in v0.18.x; B will use the lanIP of C as C's endpoint and vice versa so they will be able to ping each other over wg
