A new Request for Comments is now available in online RFC libraries. RFC 5389 Title: Session Traversal Utilities for NAT (STUN) Author: J. Rosenberg, R. Mahy, P. Matthews, D. Wing Status: Standards Track Date: October 2008 Mailbox: jdrosen@cisco.com, rohan@ekabal.com, philip_matthews@magma.ca, dwing@cisco.com Pages: 51 Characters: 125650 Obsoletes: RFC3489 I-D Tag: draft-ietf-behave-rfc3489bis-18.txt URL: http://www.rfc-editor.org/rfc/rfc5389.txt Session Traversal Utilities for NAT (STUN) is a protocol that serves as a tool for other protocols in dealing with Network Address Translator (NAT) traversal. It can be used by an endpoint to determine the IP address and port allocated to it by a NAT. It can also be used to check connectivity between two endpoints, and as a %keep-alive protocol to maintain NAT bindings. STUN works with many existing NATs, and does not require any special behavior from them. STUN is not a NAT traversal solution by itself. Rather, it is a tool to be used in the context of a NAT traversal solution. This is an important change from the previous version of this specification (RFC 3489), which presented STUN as a complete solution. This document obsoletes RFC 3489. [STANDARDS TRACK] This document is a product of the Behavior Engineering for Hindrance Avoidance Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
