I am getting this error in ISA 2004, I wasn't aware there is a limit to how much traffic a client can receive, or ports(??) I am trying to get SWAT4 working which has been nothing but a real duch bag. In the readme they Virgin Games says open 10480-10483 TCP and UDP. But the failed to add that GameSpy's server searcher (built in the game) opens ports too, like 28910 TCP. Anyhow as soon as I figured out the 10480 nonsense I started seeing 1050-1060 and 1140-1150 wanting access (look like SERVER IPs) and that's were I started getting the above error message, so even though I ad their ranges in ISA ignores the rule and blocks them anyways.
