PortForward

Servers hosted from PC's at home will need to have ports forwarded to allow incoming connections to the host PC. This is usually done within the router's configuration. The instructions for port forwarding vary per router so they won't be listed here, but here's a webpage with plenty of information: portforward.com ... You'll need to open UDP and TCP ports for the server and HTTP connections. The default ports are 22000 for both, but these can be different depending on server configuration.
