Abstract

This memo defines the NSIS Signaling Layer Protocol (NSLP) forNetwork Address Translators (NATs) and firewalls. This NSLP allowshosts to signal on the data path for NATs and firewalls to beconfigured according to the needs of the application data flows. Forinstance, it enables hosts behind NATs to obtain a publicly reachableaddress and hosts behind firewalls to receive data traffic. Theoverall architecture is given by the framework and requirementsdefined by the Next Steps in Signaling (NSIS) working group. Thenetwork scenarios, the protocol itself, and examples for path-coupledsignaling are given in this memo. This document defines an Experimental Protocol for the Internet community.
