How to Block AIM Express.

By Jessica Lynn ·
We've recently put a no Instant messanger policy on the books and blocked IM ports and IP at the firewall level. However, AOL now has AIM Express which allows instant messenging by-passing port 5190. Does anyone know how to block this? I believe all I would have to do is block access to the site, but I only know how to block access to the IP address.

Please help. The AIM Express address is http://www.aol.com/aim/aimexpress.html.

Please feel free to email me at jmerulla@cwcainc.com
Thanks a bunch

How to Block AIM Express.

by Some Guy in Seattle In reply to How to Block AIM Express.

You say "on the books." Do the employees know this, and have they seen/signed an internet acceptable use document? If you are serious about things like this, then you need to do this. Also make clear that activity is monitored and action will be taken if standards are violated.

Secondly, some firewalls can block by DNS. A quick connect to AIM express and a netstat shows that the server I connected to (probably one of hordes) is called toc-m01.blue.aol.com, IP 64.12.163.199. I didn't go into much more analysis but you could probably block a range of addresses around this one or by the domain "blue.aol.com" and take care of this.

Hope that helps -

If anyone is still looking for this. I found a great program called TerminatorX (http://blockaim.port5.com/) It's cheap $255 for a site license.

It runs as a process on the machine (but not in the task list). You can use it to block chat, IM, Internet radios etc.

It's worth a look.
