You have to bypass NAT for the IPSEC Traffic. Please refer the below URL for details. In your case, I would configure a different IP Network for the VPN Pool and configure the router to bypass NAT for traffic from your LAN to the VPN Pool of IP Addresses.

Dear Arul,

Thank you very much for your help. I changed the VPN pool and I tryied to change the VPN type(please see the attached file). The VPN client I was doing the test with is a Microsoft VPN with basic configuration and static DNS IP addresses. If I use public IP address, the VPN works like a charm. If I am behind a NAT, I still can connect but I don't have access to anything. Please hewlp me understanding what's wrong. Thank you!

Best Regards,

Aurelian
