We got two Customers that want to connect to our Datacentre. But both customers have the same IP-Range and both don't wanna change the IP-range. See image/attachment.
All Firewalls are Fortigates, except Customer 1.
What is working now:
-Customer 1 : Connects to Vlan1001 only.
-Customer 2 / Site 2 : Connect to Vlan1002 only.
-Customer 2 / Site 3 : Connect to Vlan1002 only.
-Customer 2, Connection Site 1 to 2 - Connection Site 2 - 3 - Connection Site 1 - 3
How can I resolve this for Customer 2 Site 1 and keep the Site-to-Site connections for Site 1 - 2 -3?
