Abstract
The invention determines if a security association (SA) extends end-to-end between a source node originating a connection and a destination node. In such a case, there will be no ambiguities in routing due to network address translation, and the SA is allowed. In the preferred embodiment, both end nodes of a security connection test themselves and the remote node for gateway status to determine if any ambiguities might exist in network routing due to the presence of a network address translator.
