RE: MS Exchange 5.5 serverWhat you are talking about is the "T"-suffixed
version of IOS which includes CBAC (Context-Based Access Control). It has
improvements on regular access-based lists, but it is not a firewall in the
sense of FW-1.
Since we have it on our router, I use CBAC (together with reflexive access
lists) as a first line of defense. I already have an issue open with Cisco
though because CBAC-SMTP does not support ESMTP (causing many Solaris
sendmail systems to fail to deliver inbound messages).

Subject: Cisco IOS Firewall
Dear list,
I have recently been offered by our administration to have the
Cisco IOS firewall installed on a router to the internet as our firewall
instead of using a product like Firewall-1, FreeBSD, MS ISA Firewall or some
Linux based option. From what I can gather, this is not the PIX installed
on a router but a firewall implementation (session and application proxy) of
the Cisco IOS. Has anyone used this product? Does it meet the standards of
a secure firewall product? Do you know of any issues with this product I
should take into consideration before accepting the proposal?
Thanks for any assistance.
