IOS config for public IP pass-through?
computerhighguy: Would 64.x.x.1 be assigned to a serial subinterface? I'm presently dynamically and statically NAT'ing the 64.x.x.0 subnet, and have not had to assign 64.x.x.1 to any interface. I guess what I hear you saying is if I assign firewalls 64.x.x.2-7, each would need the 64.x.x.1 as... -
