Problem with that is you can spec those ports pretty much at will. This came up on the focus-ids@securityfocus list last week. Policy is a good place to start. Make it obvious that your org does not approve of this type of thing. Then start looking at tcpdump output to find the ports/people, and go from there. toddler On Sun, 6 Jan 2002, James wrote:
What kind of games specifically?
Like online Java games (Bejeweled)? Or games like Quake, Unreal, Tribes etc?
The latter is much easier, just block all traffic to/from the default ports which use them. A quick google would yield what they use. I'll give you a quick hint and say Quake3 is 29760-5 or so and Tribes1/2 is 28000-28005 or so.

Does anybody know of any good software or way to restrict Internet gaming on a corporate Network?
