Strange Connection Problem

[Suprano]

Hi there,

i am running debian amd64, 3.8 Ghz , 2GB Ram and a borked(as in grafiks and pixel errors) geforce 7.9.

When i connect to a server (one that uses no NAT technic) it connects, and loads the map and well everything normal.

However, if i do the exact same a second time, it won't connect to the server anymore. as in, it does not load the map, but keeps saying
"connecting to server" until it times out.

I tryed a different server, but everywhere the same. it just won't connect anymore after the first time.

Any idea what this could be?
