ports for CS:S

[nighthawk3001]

Right now I am trying to figure out which ports need to be forwarded in order to allow srcds to communicate with the outside world.

I already know about TCP port 27015, but are there any other ports I need to forward?

27000 to 27015- UDP, 27030 to 27039- TCP, 1200- UDP, 27020- UDP, 27015- TCP

There a many posts about this ...

It's easier to say 27000-27040 UDP/TCP since the other ports in this range are used by unknown or nonexistent protocols
