Point to Point Configuration

Good Morning All,

I am currently working on configuring a new Point to Point connection (L3) between multiple sites.

Site A and B are able to communicate, but I cannot get communication to site C working. The sites are setup as follows:

Site A:

1811 Router (10.96.16.254)

Internet Gateway (10.96.16.250)

Site B:

2911 Router

WAN Connection (for ipsec connections / site B internet, etc)

Internet Gateway for Site A (10.96.17.250)

Site C:

2951

WAN Conneciton (for ipsec connecitons / site C internet, etc).

Site A and B communicate with no problem. Site B and C communicate with no problem. Site A and C cannot communicate.

Traffic should be flowing as follows:

From Site C across VPN Tunnel to B, Across Point to Point to C.

I can see traffic being allowed across the VPN tunnel to site B (for site A subnet), but traffic never reaches C.

Okay. I think I have this narrowed down now.

Traffic from C to A passes through the VPN tunnel, but it all passes through as the IP address of the Internet Gateway for B.

Is it possible to NAT the traffic coming from the Point to Point connection, so it passes through as a different address?
