Set up NAT on cisco 2811

Good morning, i have a branch router that connects to mpls WAN.  Also has a second interface that is used for dmvpn failover in case WAN goes down.

We want to use this second interface also as the primary internet circuit for the branch.  I changed the default route to the next hop address on the other side of the second interface and expected this to work.

But i was told i need to set up NAT for this to work, and set up an ACL for NAT to use.

Does anyone know how to set up NAT?
