Firewall and 2851?

[FireCaptKevin]

Looking at using a 2851 at main office, having 3 T1's (each have 2801 on other end) and all will come through the 2851 for Internet access. Do I need an external Firewall (I guess, like a PIX) or does the 2851 have a decent firewall for me to use? New at Cisco networking. Thanks in advance.

I'd go separate,... wait I already did. Recommend you get PIX firewalls if money is not a problem. Let the router do routing, and the firewall do packet inspection and filtering.
