Port Forwarding
The Shores of Hazeron program uses the ports 16757 to 16783 to make connections to the servers. The servers do not make connections back to the client, so you do not need to set up port forwarding. However, if you are using a firewall that blocks outgoing connections, you will need to either allow Shores of Hazeron or allow outgoing traffic on those ports.
