First, I'm using a PIX 515E. I didn't see a PIX forum on here, so I'm trying the next closest thing.
Here we go: There seems to be many IP Addresses that AIM uses to login so I blocked a range of IP Addresses in my rules:
(64.12.0.0)
+
(205.188.0.0)
along with port 5190 on a separate rule from any 'inside' to any 'outside'.
This does seem to work in denying AIM functionality on my network. However, it also blocks AOL.com and any ability to check AOL e-mail. My question is, how can I create a more specific rule entry without having to create a separate rule for every single IP that correlates to login.oscar.aol.com? I'm new to PIX so I've been using the GUI so far to do this. Is there any way to specify hostnames instead of an IP so I could just create one rule for say login.oscar.aol.com?
