we're hard at work improving multiplayer server listing/finding. Specifically, we're looking to make the process much easier, without having to mess with port-forwarding or the dreaded static-NAT issues. That's why you might be seeing some chaff in the coming weeks regarding that. So, sincere apologies if this causes trouble. Also, we're aware that LAN discovery is flaky, and it's being looked into.
* You can browse servers online (but clicking the IP does not work yet). * There's a JSON api you can query (but we make no guarantees that it will remain as-is, as it's still under development). * NAT punching (udp hole traversal, STUN) works for all servers advertising with our list. * We offer relay services for servers that cannot punch through their enemies players NAT.
