Abstract:
A method for routing IP packets with IPSec AH authentication is disclosed. The method includes locating overlay edge routers between private domains and their associated NAT routers. Outbound packets from a source private domain are modified by its overlay edge router to include IPSec AH authorization data computed using IP source and destination addresses that match a packet's final source and destination IP address upon final NAT translation immediately prior to delivery to a host of a destination private domain.

Claim (Index 1):
A method for processing an Internet Protocol (IP) packet, the method comprising:\n receiving, by a first router within an overlay network, the IP packet from a source host device associated with a source domain, the IP packet bound for a destination host device associated with a destination domain; determining, by the first router, a private IP address of a second router within the overlay network, the second router being associated with the destination domain; processing the IP packet by the first router, including:\n calculating authentication data using a public IP address of an intermediate router associated with the source domain as a source IP address, and the private IP address of the second router as a destination IP address; \n modifying the IP packet to include the authentication data; and \n generating an outer header for the modified IP packet, the outer header including a private IP address of the first router as a header source IP address, and the private IP address of the second router as a header destination IP address; and \n transmitting, by the first router, the modified IP packet to the intermediate router.
