TCP Encapsulation of Internet Key Exchange Protocol (IKE) and IPsec Packets
RFC 9329

Received changes through RFC Editor sync (created alias RFC 9329, changed title to 'TCP Encapsulation of Internet Key Exchange Protocol (IKE) and IPsec Packets', changed abstract to '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 (SA) 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.

TCP encapsulation for IKE and IPsec was defined in RFC 8229. This document clarifies the specification for TCP encapsulation by including additional clarifications obtained during implementation and deployment of this method. This documents obsoletes RFC 8229.', changed pages to 30, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2022-11-30, changed IESG state to RFC Published, created obsoletes relation between draft-ietf-ipsecme-rfc8229bis and RFC 8229)
