Playing Kong with your friends either over a LAN or the internet is easy. One player should create a server (usually the one with the fastest connection and most powerfull machine) while the other players look for it in the list of servers. The server will appear provided that the computers are either all on the same local area network or all connected to the internet. In some cases the server may appear but clients are unable to connect; This is most likely because the server is behind a NAT (one internet connection shared between several computers through a router) or has a firewall enabled. In the case of a NAT it is necessary to configure the router to forward UDP network traffic to the server computer on the port the server is running (the default port is 5454). For more information on port forwarding and how to accomplish it please visit the following website: http://www.portforward.com/. In the case where a firewall is active and preventing players to connect, it should be re-configured to allow traffic through the given port.
