Another question I had was related to external e-mail accounts, such as aol.com or msn.com. Is there a way to block users from having access to their external e-mail accounts, without denying them access to aol.com (example) all together? -----Original Message----- From: Aeon Hale [mailto:[email protected]] Sent: Tuesday, February 05, 2002 2:10 PM To: [email protected] Subject: Re: [FW-1] How to block instant messenger traffic default message port for AOL is TCP 5190, but you must block more than that. Do nslookup for login.oscar.aol.com and block those IP's. You can setup a rule before this AOL drop rule to allow only certain IP's to talk to AOL servers (or just exclude them in the same drop rule). As far as allowing AOL internal and not external, i dont see how that would be possible since you need to log into AOL servers to use IM and i'm not sure you can block buddy lists. But i'm not an authority on AOL. Hope this helps, Aeon -----Original Message----- From: Christopher Planell [mailto:[email protected]] Sent: Tuesday, February 05, 2002 1:43 PM To: [email protected] Subject: Re: [FW-1] How to block instant messenger traffic I would be interested on how to block AOL Instant messenger, and if there is a way to punch a hole to allow only certain users by IP address (external use). Also is there a way to allow internal use ONLY. -----Original Message----- From: Chris Arnold [mailto:[email protected]] Sent: Tuesday, February 05, 2002 12:29 PM To: [email protected] Subject: Re: [FW-1] How to block instant messenger traffic Which one?
