            NAT/Firewall NSIS Signaling Layer Protocol (NSLP)


   This memo defines the NSIS Signaling Layer Protocol (NSLP) for    Network Address Translators (NATs) and firewalls.  This NSLP allows    hosts to signal on the data path for NATs and firewalls to be    configured according to the needs of the application data flows.  For    instance, it enables hosts behind NATs to obtain a publicly reachable    address and hosts behind firewalls to receive data traffic.  The    overall architecture is given by the framework and requirements    defined by the Next Steps in Signaling (NSIS) working group.  The    network scenarios, the protocol itself, and examples for path-coupled    signaling are given in this memo.
