This document describes an extension to the TCP Authentication Option (TCP-AO) to support its use over connections that pass through network address and/or port translators (NATs/NAPTs). This extension changes the data used to compute traffic keys, but does not alter TCP-AO's packet processing or key generation algorithms.
