Help with network design/routing

We have 2 sites (labeled SITE #1 and SITE #2 on the diagram). These 2 sites are connected together via a 1g link. We are partnering with 2 remotes sites (labeled REMOTE #1 and REMOTE #2 on the diagram). These remote sites manage their own networks and firewalls.

  • Site #1 connects to remote #1 via a 50m evpl
  • Site #1 connects to remote #2 via VPN

We have a need for an interpreting service from all 4 locations. The MPLS connection from us to them will be from SITE #2, and all 4 sites should be able to access the interpreter service through this site. Devices at any of the locations should be able to register their ipads/phones etc. using the interpreter service app and an IP provided by them. These devices should be able to access any IP in the 10.140.x.x range at the interpreter service location(s).

For Site 1, Site 2, and Remote 1, this will not be an issue because there is no network overlap. For Remote #2, they already use 10.140.x.x, which is what the interpreter service uses. We are looking for a way to have Remote 2 be able to access the interpreter service while also limiting the NAT configuration on the SITE 1 side. Since we do not manage these remote locations, we'd prefer any additional config for this be on their end, but I fear this may not be completely possible.

What are my options for allowing remote #2 access to the interpreter service applications (10.140.x.x) when they already use those addresses on their local network?
