FortiClient IPSec VPN keeps connecting to a wrong remote IP

Hi There,

I just installed a FortiClient on a Win11. After configuring a IPSec VPN, I tried to connect it, but it connected to a different remote IP from what I input. (I checked it on Resource Monitor)

Our FortiGate gateway IP should be 72.x.x.x, which is what I input on the IPSec connection, but the IPs it connected were 172.67.x.x and 104.x.x.x. (I re-created the IPSec profile once, so the IP changed after re-creating profile)

It's so weird. Only on that laptop, and our other computers are all good. Any one had the similar experience? Thanks.

Daniel
