Cisco IOS Firewall

Title: RE: MS Exchange 5.5 server

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.     Lindsay Mieth
