I have three sites A,B and C

Site B terminates 1 S2S VPN tunnels from site A and site C each.

The Vpn tunnels are up. I need to route traffic from site C to Site A and vice-versa. I also need to Nat the traffic from site C to site A at site B.

I am using cisco 2800 router at site B.

Where can I get a cofiguration example for this?

Please help with any Idea.
