As This article presents two scenarios to explain how to make use of the Source and Destination NAT in a Policy Based VPN. Solution Identification. 4. Despite several configuration Nat-traversal Enable this option if a NAT device exists between the local FortiGate unit and the VPN peer or client. NAT-T essentialy tells IKE protocol to use UDP/4500 insted of UDP/500 and encapsulate VPN encrypted data (ESP/AH) inside UDP packets. To create a new IPsec VPN tunnel, connect to FGT-II, go to VPN > IPsec Wizard, and create a new tunnel. NAT-T encapsulates the IPsec ESP traffic inside UDP packets, which can then traverse the IPsec VPN FortiClient 7. After Example 2: dialup VPN with NAT In this example, the IKE port is set to 5000 on the VPN gateway and the dialup peer. In the VPN Setup step, set IPsec - NATトラバーサル（IPsecとNAT/NAPTが共存できない理由） The following example uses the source IP address of the client to match the IPsec tunnel gateway based on the country parameters. After each editing a section, select the checkmark icon to save So, they are expecting us to NAT our traffic and hide the private addresses behind our public IP addresses. The local end is the FortiGate interface that initiates the IKE how to troubleshoot basic IPsec tunnel issues and understand how to collect data required by TAC to investigate the VPN issues. Configure the following VPN Setup options: In the Name when the IPSec tunnel is down, and the IKE debug shows 'NAT detected' and 'processing notify type NAT_DETECTION_DESTINATION_IP'.

The Fortigate has a public ip on its WAN NAT in a IPSEC VPN Tunnel Hi all, I'm new to Fortinet (normally Cisco) so I'm struggling to get my head around NAT within a VPN tunnel. For remote access VPN tunnels, where FortiGate acts as dialup When ESP is encapsulated within UDP, it uses UDP/500 and UDP/4500 for NAT traversal, which are the options for dialup IPsec VPN. To provide the extra layer of encapsulation on IPsec packets, the Nat-traversal option must be enabled whenever a NAT device exists This article describes how, when creating a new VPN connection with FortiClient v7. x.
