Log into the primary FPC CLI and run the command diagnose vpn tunnel list <phase2-name> to show the sessions for the phase 2 configuration. The example below is for the to-fgt2 phase 2 configuration configured previously in this chapter. The command output shows the security association (SA) setup for this phase 2 and the all of the destination subnets .

From the command output, make sure the SA is installed and the dst addresses are correct.
