Technical Summary

This document specifies the behavioral properties required of the
Network Address Translator (NAT) devices in conjunction with the
ICMP protocol. 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.
