Firewall features on Cisco 2821 ISR(C2800NM-ADVENTERPRISEK9-M)

Unanswered Question
May 24th, 2007

If you're comparing PIX or ASA with Security features on C2821 ISR, Are these security features on C2821 ISR just as good as PIX or ASA ?

Is it good enough to replace the PIX or ASA facing the internet ?

I have this problem too.

Though Cisco does provide you with these FW features in the ISR series, It cannot be considered to be a replacement for a PIX or a ASA. The basic fw functionality would be okay with ISR router but as the load increases on the router you might face problems. Its best to seperate these functions in different boxes.
