Description of Working Group

The goal of the Authenticated Firewall Traversal Working Group is to specify a protocol to address the issue of application-layer support for firewall traversal. The working group intends to specify a traversal protocol supporting both TCP and UDP applications with a general framework for authentication of the firewall traversal. To promote interoperability, the group will also propose a base authentication technique for use within the general authentication framework.

The output of the group will consist of a standards-track RFC(s) describing the traversal protocol, the base authentication methods and a reference implementation of the protocol, and base authentication methods. The working group will start with the SOCKS system described by David Koblas in his paper presented at the 1992 Usenix Security Symposium.
