NAT on incoming WAN connection

pmorehead

Level 1

I have an edge router configured for ip unnumbered on the T1 serial i/f using the ethernet address 65.200.14.97/27. I now need to bring a WAN connection into this same router with another WIC to a 2611 w/1MFT-1 WIC. The WAN link works for ip ping both ways accross the WAN link. I have been unable to NAT the remote IP subnet succesfully across the Internet Edge router just using NAT Overload to single IP address. Does IP unnumbered causing a problem?

Existing perimeter router is Cisco 2610 and has the following statements:

Serial 0/0 (T1 WIC-1DSU)

ip unnumbered Ethernet 0

(tried ip nat outside statement here,,,didn't work)

Ethernet 0

ip address 65.200.14.97 255.255.255.224

Serial 0/1 (New interface)

ip address 10.10.10.1 255.255.255.0

ip nat inside

ip nat pool ovrld 65.200.14.117 65.200.14. 117 netmask 255.255.255.224

ip nat inside source list 1 pool ovrld overload

access-list 1 permit 10.17.0.0 0.0.0.255

ip route 0.0.0.0 0.0.0.0 65.200.14.96

The remote subnet to connect is 10.17.0.0/24

remote router is Cisco 2611 w/1MFT-1 WIC

serial 0/0:1

ip address 10.10.10.2 255.255.255.0

ethernet 0/0

ip address 10.17.0.233 255.255.255.0

ip route 0.0.0.0 0.0.0.0 10.10.10.1

I can ping from the remote router to 65.200.14.97, but can't get beyond that point......
