Ok here is the situation. Two sites, Office-A, Office-B. Each site has a dedicated T1 for internet. There is also a p2p T1 between both sites that is used to access servers from the opposite sites.

Each side has a cisco 3725 router. Office-B has lost a wic card for the internet t1.

What I want to do is route all the internet and lan traffic from Office-B to Office-A. The lan traffic meaning that client computers at Office-B have to access servers at Office-A.

Office-A:
Serial0/0 - Internet T1 - 66.66.66.66 (fake public ip)
Serial0/1 - p2p T1 - 10.255.255.1
Routing:
ip route 0.0.0.0 0.0.0.0 66.66.66.65
ip route 172.18.0.0 255.255.0.0 10.255.255.2

Office-B:
Serial0/0 - Internet T1 - 77.77.77.77 (fake public ip)
Serial0/1 - p2p T1 - 10.255.255.2
ip route 0.0.0.0 0.0.0.0 Serial0/1

Currently Office-B can access Office-A servers and vice versa with no problems. BUT Office-B has no internet. I ran a traceroute to google.com and here is what it showed:

1. 10ms 10ms 10ms 77.77.77.77
2. 3ms 3ms 2ms 10.255.255.1

Correctly asked questions will receive a better answer.
 
You need

ip nat inside

on ALL interfaces of Router B(outside and inside interfaces, since they're all private RFC1918 IP subnets), and include router B's subnet(s) in the NAT acl in router A.
