NAT Question

What is incorrect with the below PAT/NAT configurations... for the below routers? No NAT translations are occurring. The topology is as follows.

ISP --- Cust1 --- Branch1

 

Double NAT is being used. A multilayered switch is connected to Cust1. Vlans have IP addresses on the switch that must be translated by Cust1. Branch1 has IP addresses that must be translated by Cust1, too. Both, the switch and routers must be able to ping the router on the other side of the PPPoE connection. Why are no translations occurring?

 

Please see the attached file for config details.

Outcomes will be copied to the below file.

How shoulst.txt (file with should-be outcomes of NAT), will be determined, is from the translation outcomes.
