When I run two servers on the same port, it doesn't show up one, just as I ran only one of them...
You can't run two servers on the same port, that may be your issue. Both
servers have to run on a seperate port.

People setting up Unreal servers behind firewalls have been asking for a summary of the TCP/IP ports Unreal uses. Here goes:
* UDP 7775 and 7776 are used only for LAN games. You don't need to route them through a firewall.
* UDP 7777 is for gameplay.
* UDP 7778 is for server querying.
* UDP 7779+ are allocated dynamically for each helper UdpLink objects, including UdpServerUplink objects.
* UDP 27900 is for server querying, if you enable the master server uplink. Some master servers use other ports, like 27500.
When players try to connect to an Unreal server, they connect to port 7777 by default.
Optionally, the server administrator can specify a different game port than 7777 with the "port=" command line parameter, for example: "Unreal.exe -server port=8888". In this case, contiguous port numbers are used for helper objects: 8888 for gameplay, 8889 for querying, 8890 for helper UdpLink objects, etc.
