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.
