Does NAT-T only work when 2 NAT devices are between the VPN server and remote clients? Is it best practice to use NAT-T for VPN? Any ideas, suggestions, recommended workarounds are welcome. FIRST - NAT-T must be enabled in IKE Parameters in order for any connection to have NAT-T working NEXT - EnableNAT-T on the individual crypto map for the IPSec connection.

Route-Based and Policy-Based VPNs with NAT-T date_range 27-Sep-20 Network Address Translation-Traversal (NAT-T) is a method used for managing IP address translation-related issues encountered when the data protected by IPsec passes through a device configured with NAT for address translation. 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 the case if your ISP is doing NAT, or the external interface of your firewall is connected to a device that has NAT enabled. As well as IPsec providing confidentiality, it also provides authenticity and integrity.

NAT traversal (NAT-T) prevents intermediary devices from applying NAT to VPN communications if NAT is found to prevent the NAT-T encapsulates the Quick Mode (IPsec Phase 2) exchange inside UDP 4500 as well. After Quick Mode completes data that gets encrypted on the IPsec UDP Encapsulation of IPsec Packets for NAT Traversal, on page 3 running Cisco IOS Release 12.2(13)T. If both VPN devices are NAT-T capable, NAT IPsec VPN uses a different protocol (ESP) for the actual data transfer than for establishing the connection (IKE).

NAT-T. By default, an ASA will encapsulate both IKEV2 negotiation and the IPSec encrypted packets in UDP 500. If you want to use NAT-T and encapsulate the IPSec packets in UDP 4500 then oort forward UDP 4500 on the NAT router and enable NAT-T on the each ASA: Cisco VPN 3000 Client and Concentrator Release 3.6.1 and later for NAT-T The information in this document was created from the devices in a specific lab environment.
