IPSEC VPN problem

[ayoubzamame]

I am new to Fortinet FortiGate, and I currently have a FortiGate 40F device. My objective is to establish a remote access VPN using the IPSec protocol.

To create the VPN, I followed the wizard and added a policy in the firewall configuration.

However, I encountered an issue where I can connect to the VPN using my private IP address, but I am unable to connect using the public IP address. Could you please assist me in resolving this problem?

could you provide more detail? What do you mean with "public IP address". 

Basically if you did not enable mode config and ip assignment or dhcp over ipsec - traffic that goes through the tunnel will hit your Fortigate with your PCs IP as source ip.

Could you please specify more about topology, Need to know about private ip address where that machine is located.
