This attribute specifies the IP address of the NAS gear that requests service on behalf of the client computer. Each implementation may customize the use and behavior of this attribute, but the RADIUS RFC does not permit both this attribute and the NAS-Identifier attribute to be used in the same packet. However, one of the two must be present in any packet.
