IETF RFC 5508
April 2009
Abstract:
This document specifies the behavioral properties required of the
Network Address Translator (NAT) devices in conjunction with the
Internet Control Message Protocol (ICMP). The objective of this memo
is to make NAT devices more predictable and compatible with diverse
application protocols that traverse the devices. Companion documents
provide behavioral recommendations specific to TCP, UDP, and other
protocols.
