WIC-1E As outside interfave on 1750 to cable modem network

I have a 1750 with the 2nd ethernet card added to it. I have the 2nd card set up to DHCP an address from my cable modem network and have the default route set to that interface. I am unable to ping or get out to the internet. If anyone has information please help. Also i am natting from the inside (f0) interface to the oueside(e0) interface

You’re natting to another IP address that your ISP provided? It should work as long as it’s either on the same subnet or routed to the ISP gateway. You might want to have your configuration looked over with your ISP or Cisco.

I have never heard of anyone DHCPing an address to a router interface. What is the logic/advangage?
