I'm working on a Cisco 2800, trying to get it to NAT an internal RFC1918 to a WAN. The WAN (ISP) address is from DHCP. I've never worked with NAT on a Cisco before. Cisco's tech pages are also listing some commands that don't exist in the 2800. Please see
sh run output below. Hopefully, someone sees what I'm leaving out. I can ping from each interface to its' connected network, but cannot cross the router.
