If the virtual private network (VPN) server is behind a NAT device, a Windows Vista or Windows Server 2008-based VPN client computer can't make a Layer 2 Tunneling Protocol (L2TP)/IPsec connection to the VPN server. NAT can break a VPN tunnel because NAT changes the Layer 3 network address of a packet (and checksum values), whereas the tunneling, used by an IPSec or L2TP VPN gateway, encapsulates/encrypts the NAT-T is used to detect NAT device in the path and change port to UDP 4500. This UDP port 4500 is used to PAT ESP packet over ipsec unaware NAT device. if this UDP encapsulation in not done then the ESP packet will be dropped and data will not flow.

It is the preferred method because it works well even when peers are located on different private networks protected by a firewall and NAT. No special configuration on the NAT device is required. You need no permission by your network administrator of the NAT. The built-in NAT Traversal Function opens a "Punched Hole" on the NAT or firewall. When the VPN Client or VPN Bridge attempts to connect to your VPN Server behind the NAT, the connection packets will be lead through the hole. Network Address Translation-Traversal (NAT-T) is a method for getting around IP address translation issues encountered when data protected by IPsec passes Nat Traversal, also known as UDP encapsulation, allows traffic to get to the specified destination when a device does not have a public IP address. This is usually NAT-T is an IKE phase 1 algorithm that is used when trying to establish a IPSEC VPN between two gateway devices where there is a NAT device in front of one Network address translation traversal is a computer networking technique of establishing and maintaining Internet protocol connections across gateways that  NAT traversal in VPNs.

What is use in Site to Site VPN with NAT -T wireshark capture and LAB 1 – the VPN server is behind a NAT device ; 2 — both VPN server and client are behind a NAT. Just restart your computer and make sure that the VPN tunnel is established successfully [alert] If both Windows VPN server and client are behind NAT, you need to change this setting on both devices. A VPN tunnel cannot be established if both the destination network and the local network have the same subnets. The Apply NAT Policies feature or NAT over VPN is configured when both sides of a proposed site to site VPN configuration have identical, and hence overlapping, subnets. To pass through multiple outgoing IPsec tunnels, it requires that both the VPN client and server support NAT-Traversal (NAT-T). Without NAT-T, it only allows one outgoing IPsec VPN at the same time. L2TP with IPsec policy is in transport mode, which can only pass through NAT if both VPN client and server support NAT-T (Note: All Vigor Router support NAT-T). NAT traversal es un término aplicado a las técnicas que establecen y mantienen conexiones en redes utilizando los protocolos TCP/IP o UDP que atraviesan (NAT) gateways.
