Blable101 Follow the waw custom games guide to have an idea on playing with friends in waw. Then follow the lan section. You can skip port forwarding/upnp since it's not needed for lan. Also, when connecting to host make sure you use the correct port when connecting to them. The host can check that by using net_port and other joining players would reference that to connect to them connect ipv4:port.
