The IESG has approved the following document: - 'NAT Behavioral Requirements for Unicast UDP ' <draft-ietf-behave-nat-udp-08.txt> as a BCP This document is the product of the Behavior Engineering for Hindrance Avoidance Working Group. The IESG contact persons are Magnus Westerlund and Lars Eggert. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-behave-nat-udp-08.txt Technical Summary This document defines basic terminology for describing different types of NAT behavior when handling Unicast UDP and also defines a set of requirements that would allow many applications, such as multimedia communications or on-line gaming, to work consistently. Developing NATs that meet this set of requirements will greatly increase the likelihood that these applications will function properly. Working Group Summary There has been some disagreement with default NAT binding timers in general, and specific concern around handling of specific applications such as DNS which don't need 2 minute timeouts Protocol Quality No new protocols are defined in this document, rather, this document describes how NATs should function when NATting UDP packets. The WG is confident that this document captures the behevior of NATs typically sold to consumers. The document was reviewed for the IESG by Magnus Westerlund. Proto Shepherd was Dan Wing. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
