I'm trying to create and join a multiplayer game that has been created from a custom UDK installation.
It works correctly when two (or more) instances of the game are created on the same computer and are connected over localhost by running the following commands:
udk.exe server map_name udk.exe 127.0.0.1
The problem comes when trying to connect to the game server over a LAN (with the command
udk.exe server_ip_address); the clients are unable to connect and the default map is loaded. The server log reports a client disconnection from the computer trying to connect. The client log reports the error,
Error: Can't start an online game that hasn't been created.
Both computers are able to ping each other, as well as both having their firewalls disabled. Many combinations of the command-line arguments for starting the server have been tried. Creating an installer from the server machine and installing a fresh copy of the game on the client has also been tried.
Any solutions on how to solve this issue would be appreciated.
