A FortiGate is configured for a dial-up IPsec VPN to allow multiple remote FortiGates to connect to it.
However, FortiGates A and B have problems connecting to the VPN. Only one of them can be connected at a time. If site B tries to connect white site A is connected, site A is disconnected. The IKE real time debug shows the output in the exhibit when site A is disconnected.
Which configuration setting should be executed in the dial-up configuration to allow both VPNs to be connected at the same time?
 set enforce-unique-id disable
 set enforce-unique-id disableA.
set add-route enable
B.
set single-source disable
C.
set route-overlap allow
D.
