#VPN Site-To-Site. Issue When Create Multiple Tunnels
I have 3 Site A B C using FortiGate-VM (7.0 & 7.2). Three Site using 3 Ip Public for VPN gateway.
IPsec Tunnel between A <-> B is Up and running.
And I create another Tunnel A <-> C, But the Wizard show "Unable to setup VPN. The rollback process has encountered an error. Orphaned objects may still exist in the configuration database".
