i don't understand "dreadless" my en->de dictionary does not find it (and it uses fuzzy search),
but CS uses:
protocol: UDP(IP)
server port: 27015 (the port the player connects to, that is a default, a lot of servers used different ports around 27015)
client outgoing port: <random> (between 1024 and 65000)

cheers
