Abstract: This invention provides a method for providing network security services, such as those provided by the IPSEC protocol, through network address translation (NAT). The method is based on determining the transformations that occur on a packet and compensating for the transformations. Because only TCP and UDP protocols work through NATs, the IPSEC AH/ESP packets are encapsulated into UDP packets for transport. Special operations are performed to allow reliable communications in such environments.

Abstract: A method, device, system and computer program for providing a transport distribution scheme for a security protocol are disclosed. A first packet data connection is established to a remote node for transmitting packet data over a network with a security protocol. An authentication procedure is performed with the remote node via the first packet data connection for establishing a security protocol session with the remote node. At least one security parameter is negotiated with the remote node for transmitting packets through the first packet data connection. A second packet data connection is established to the remote node, and at least one security parameter is negotiated with the remote node for use with the second packet data connection. The first and second packet data connections are handled as packet data subconnections associated with the security protocol session.
