If you are using a router you need to access its configuration page (this is usually done by typing http://192.168.0.1 in your browser). In the port forwarding section of the router configuration page, you need to forward UDP port 7845 (for ZSNES) and TCP port 4000 (for zbattle.net downloading) to your LAN IP. For more information on how this is done, please consult your router manual.
If you are using a firewall you need to allow incoming/outgoing UDP port 7845 (for ZSNES), outgoing TCP port 4398 (to connect to the zbattle.net server), and incoming TCP port 4000 (for zbattle.net downloading). For more information on how this is done, please consult your firewall software documentation.
