RE: Blocking Internet Gaming
It would make me nervous too. Plus, I hate when things stop working because then people call me and I have to talk to them :) But if a brand new packet is outbound to 29760, you know it is probably going to a Half Life server (I think that's the port). So wouldn't it be wise to deny that? Specifically it would be UDP 29760, not TCP. Doesn't FTP use TCP when negotiating a connection? - James -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Scott Gifford Sent: Sunday, January 06, 2002 9:45 PM To: James Cc: [email protected] Subject: Re: Blocking Internet Gaming "James" <[email protected]> writes: > What kind of games specifically? > > Like online Java games (Bejeweled)?

If you're not allowing incoming connections of any kind (including non-PASV FTP) it shouldn't matter, but blocking ports above 1024 always makes me nervous... ----ScottG.
