I got a 2611 router, with e0 and e1 (2 ethernet ports). I'm planning to use this as a internet gateway router, I'm using this for my home with Cox Cable internet. I'm given a dynamic ip address, notice not a static ip. How would I set it up to get dynamic ip? I know how to do static, ip address x.x.x.x x.x.x.x would be easy for static, but how would I do for dynamic? My goal is to set it up so I can later on do vpn through the same router as well.
