This document describes a method to transport Internet Key Exchange
Protocol (IKE) and IPsec packets over a TCP connection for traversing
network middleboxes that may block IKE negotiation over UDP. This
method, referred to as "TCP encapsulation", involves sending both IKE
packets for Security Association establishment and Encapsulating
Security Payload (ESP) packets over a TCP connection. This method is
intended to be used as a fallback option when IKE cannot be
negotiated over UDP.
This document is a product of the IP Security Maintenance and Extensions Working Group of the IETF.
This is now a Proposed Standard.
