Incoming ports

[patdaman45]

What are the incoming ports (from clients) for srcds? I try locking it down to only 27005 but it will not allow users to connect.

This would be our ideal method for blocking/filtering ddos attacks.

Many routers are forwarding their clientports "dynamically" for example some clients has the clientport 34955, some has 27005, other has 59664 and so on. The reason of this is, for example, if you and me are playing on the same time behind the same IP-address (external). The dynamic port-forwarding makes sure that we both can play, instead of me being angry on you because you are using the 27005 port. I hope you understood this.
