Hi,

I’m having an issue logging in to FortiClient VPN when trying to connect to my B office while I’m connected to the A office network through the FortiGate SSID.
When I disable all firewall policies, the connection works.

Could you please advise which policy might be blocking the VPN connection?

application control
FortiGate v5.0

Hi Ardmae

Re-enable all policies and enable traffic logging on each.

Once you try connect and you are blocked, check the traffic logs on the FortiGate and you will see the policy ID that blocked your SSL VPN traffic. You can filter the logs by source and destination in order to find the related traffic log quickly.
