Layer 7, TCP and UDP Ports

I want to enhance my QOS in Router with Prio highest to Warsow ;)
Can someone give me the Layer 7 pattern for wsw networkpackages?
TCP and UDP Ports are not that useful, because every serveradmin can
make there what he wants.

im not sure, but i think it doesnt matter what port the server uses, the port it answers to is on your machine and hopefully doesnt need to be the same port as the servers.

There are several ways to analyze and mark the network packets. Best would be Layer 7 other way could be via ports to priorize the traffic especially for wsw ;)
I did this for Quakelive successfully and want it the same for warsow.
