Hello, I just added a firewall in front of one of my servers and with Left 4 Dead everything works exactly the same as before.
It is running on port 22000
But on a Counter Strike Source server with port 21000 if I turn on server query it fails and keeps rebooting the server, even though it is booting up properly.

Is there a port I forgot to unblock?
I have port 20000-28000 unblocked, 1200, 3579, 1227

Thanks

Can you still query the running server with other programs?

Yes, I have not tested it again, but I have a feeling it has something to do with my firewall config. Maybe CSS uses a different port to query then L4D ?
