I'm a little confused. The literature on a 1721 router states that it is capable of Stateful packet inspection and the Cisco IOS Firewall includes context-based access control for dynamic firewall filtering, denial-of-service detection and prevention...

I' using a 1721 router and a 2950 switch. I want my cable modem connected to my router's WAN port. How do I config the router to dynamically get an IP address from my ISP? Or do I get a static IP from them.Thanks,Chris
