Abstract

This document describes a method to transport Internet Key ExchangeProtocol (IKE) and IPsec packets over a TCP connection for traversingnetwork middleboxes that may block IKE negotiation over UDP. Thismethod, referred to as "TCP encapsulation", involves sending both IKEpackets for Security Association establishment and EncapsulatingSecurity Payload (ESP) packets over a TCP connection. This method isintended to be used as a fallback option when IKE cannot benegotiated over UDP.
