This memo documents the various methods known to be in use by
applications to establish direct communication in the presence
of Network Address Translators (NATs) at the current time. Although
this memo is intended to be mainly descriptive, the Security
Considerations section makes some purely advisory recommendations
about how to deal with security vulnerabilities the applications
could inadvertently create when using the methods described. This
memo covers NAT traversal approaches used by both TCP- and UDP-based
applications. This memo is not an endorsement of the methods
described, but merely an attempt to capture them in a document.
This memo provides information for the Internet community.
This document is a product of the Behavior Engineering for Hindrance Avoidance Working Group of the IETF.
