Internet Engineering Task Force (IETF) M. Komu Request for Comments: 5770 HIIT Category: Experimental T. Henderson ISSN: 2070-1721 The Boeing Company H. Tschofenig Nokia Siemens Networks J. Melen A. Keranen, Ed. Ericsson Research Nomadiclab April 2010 Basic Host Identity Protocol (HIP) Extensions for Traversal of Network Address Translators Abstract This document specifies extensions to the Host Identity Protocol (HIP) to facilitate Network Address Translator (NAT) traversal. The extensions are based on the use of the Interactive Connectivity Establishment (ICE) methodology to discover a working path between two end-hosts, and on standard techniques for encapsulating Encapsulating Security Payload (ESP) packets within the User Datagram Protocol (UDP). This document also defines elements of a procedure for NAT traversal, including the optional use of a HIP relay server. With these extensions HIP is able to work in environments that have NATs and provides a generic NAT traversal solution to higher-layer networking applications. Status of This Memo This document is not an Internet Standards Track specification; it is published for examination, experimental implementation, and evaluation. This document defines an Experimental Protocol for the Internet community. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.
