overlapping networks

The solution will be to use vrf  Lite or MPLS.

If you are operating over a WAN you will definitely have to consider implementing mpls vpnv4 for the transportation of each vpn tunnel, as you will need to export and import route targets RT along with creating a unique route distinguisher  RD for each 1.1.1X  network so asoto keep them unique across your WAN.

A bit of Route Leaking will be involved  that will allow connectivity to your remote overlapping net from the server network perspective.
