Jul 23, 2014 · Many NAT devices do not translate the source port of IKE traffic and therefore NAT-T is not triggered. This is because most NAT devices have some sort of "IPSEC" aware NATting. The only Checkpoint device that is able to use full NAT-T support is the VPN1-edge range of devices running Sofaware.
NAT (Network Address Translation) is a feature of the Firewall Software Blade and replaces IPv4 and IPv6 addresses to add more security. You can enable NAT for all SmartDashboard objects to help manage network traffic. NAT protects the identity of a network and does not show internal IP addresses to the Internet. 5) If packet's pre-NAT source IP is in your firewall's VPN domain AND the post-NAT destination IP is in your peer firewall's VPN domain, AND the VPN column of the rule matched in #1 is "Any Traffic" or explicitly set to the matching VPN Community, source NAT then encrypt the traffic into the matching Community tunnel of which both your firewall and the peer are members. When Check Point gateway initiates a VPN tunnel with a 3rd Party peer, NAT-T is forced because it leaves the first interface IP address in NAT-D payload. The SA is established on UDP port 4500, and then VPN traffic fails. When 3rd Party peer gateway initiates the VPN tunnel, NAT-T is not used. The SA is established on UDP 500, and VPN works fine. IPSec VPN NAT-T traffic is sent to the MAC address of wrong next hop or old IP addrees. Site 2 Site VPN is established with a DAIP VPN peer using NAT-T. Clearing the 'orig_route_params' with the command: # fw tab -t orig_route_params -x -y resolve the issue until the NAT device IP changes again. When communicating within a VPN, it is normally not necessary to perform NAT. You can disable NAT in a VPN tunnel with a single click in the VPN community object. Disabling NAT in a VPN tunnel by defining a NAT rule slows down the performance of the VPN. Connecting Translated Objects on Different Interfaces
