Hi,
I'm trying to create my own server
with "dedicated server"
I checked option "register in lobby",
but I can't see it in the lobby :-(
Any help is appreciated :-)

I forwarded all the necessary ports:
23073 23073 UDP
23083 23083 UDP
27243 27243 TCP
27243 27243 UDP
27015 27015 TCP
27015 27015 UDP

and the funny thing is, that i can see ppl joining my game ..

you CAN'T see it in the lobby, because you are IN the game, if you quit the game, your ending the server.
