I have 2 independent networks and a connection between them
Now I want to make failover configuration. If ISP2 goes down all traffic form network 2 should be directed to network1 and to ISP network1 and it works but not in the way I want.
Here is a diagram of network1
The problem is that traffic from cust.2 goes directly to ISP1 but I want that traffic to go to server1 and then to ISP1 . I think that I should make some connection marks and routing marks but I don’t know how.
Here are my interfaces , NAT and routes configuration
