Possible Issue

We're setting up a connection for our aircards between us and Alltel. Our aircards will be assigned a static ip address (166.211.213.64/26) and will be routed from the Alltel network straight to us via a T1 line. I can ping the Alltel end of the T1(75.116.158.5), and I can ping our end(75.116.158.6) from the aircard. I can also ping the aircard(166.211.213.65) from our router. But I can't get past the router from any of our other devices on our network. I've set up a route on our core switch that sends all traffic headed to 166.211.194.64/26 to 10.1.1.10, which is the internal interface of our router. But if i do a traceroute to 166.211.213.65 from that switch or any other device on our internal network it dies at 10.1.1.10. Is this a NAT issue? Do we need to NAT the 166.211.213.64 subnet to a pool of internal addresses?

Thanks in advance

You need to NAT your inside host(s) to a public address to access the Internet. The problem is you are NATting the inside hosts to use the internal IP and it needs to use the outside IP. Reconfigure it as follows;

no ip nat inside source list 1 interface Ethernet0/0 overload

ip nat inside source list 1 interface Serial0/0 overload
