Attached is the capture of Forticlient VPN which is initiating from our local network. It is configured as Quick mode with mode config and the first three messages are fine .
Initial message from my network to remote FG FW via UDP 500, then from remote FG FW to my network via UDP 500 and the last message of Phase 1 from my network to remote FG FW via NAT-T.
All these ports are opened in our FW.
But I can see another Aggressive message from Server to client instead of going to mode config message.
But with the same config file, it is connecting via mobile data.
Any suggestions to resolve the issue.
