The FortiGate is used as an IPsec gateway at a branch office. Two tunnels, tunA and tunB, are established between this FortiGate and the headquarters’ IPsec gateway. The branch office’s subnet is 10.1.1.0/24. The headquarters’ subnet is 10.2.2.0/24. The desired usage for tunA and tunB has been defined as follows:
– sessions initiated from 10.1.1.0/24 to 10.2.2.0/24 must be routed out over tunA when tunA is up
– sessions initiated from 10.1.1.0/24 to 10.2.2.0/24 have to be routed out over tunB when tunA is down
– sessions initiated from 10.2.2.0/24 can ingress either on tunA or on tunB
