Question : Problem: Bonded T-1s with NAT on Cisco 1841 router

I am configuring an 1841 router with (2) T-1s. I have everything working but when I configure the Eth0/0 interface with a public IP as outlined below and Eth 0/1 with a private IP say 192.168.0.1 I can not ping it. Any ideas why?

Answer : Problem: Bonded T-1s with NAT on Cisco 1841 router

If the multilink interface connects to the outside (the internet), then yes, that interface has to be designated an "outside interface".
