       RADIUS Extensions for IP Port Configuration and Reporting
                draft-ietf-radext-ip-port-radius-ext-06

Abstract

   This document defines three new RADIUS attributes.  For devices that
   implementing IP port ranges, these attributes are used to communicate
   with a RADIUS server in order to configure and report TCP/UDP ports
   and ICMP identifiers, as well as mapping behavior for specific hosts.
   This mechanism can be used in various deployment scenarios such as
   CGN (Carrier Grade NAT), NAT64, Provider WLAN Gateway, etc.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
