Cisco ACL's to prevent Quake Arena?

[Tony Driscoll]

Hi all, As a roundabout from yesterday's thread regarding Quake Arena: anyone know of a decent way to PREVENT internal users from connecting to public Quake Arena servers using ACL's or otherwise? I know little about the game itself other than the fact that consultants shouldn't be using our T3 for head-to-head play with their virtual buddies on the weekends!  :-) It appears that the server port number can be random like most things from what I've been reading making it possibly more challenging to lock down outgoing traffic?     TIA Tony Driscoll
