Clear Subscriber Session based on the NAS IP Address
The support for Accounting On/Off messages for IPSG in server mode introduced in one of the earlier releases enabled
IPSG to act as a Radius server. On receiving a Radius Accounting On/Off message, IPSG clears all sessions mapped to
the client's L3 IP address. In certain network architectures, the L3 IP address of the Radius Accounting request message
could be a Radius Proxy device located between the GGSN nodes and IPSG. This leads to IPSG terminating all the
subscriber's sessions of all the APNs for GGSN.

With this release, the existing sessions are cleared based on the NAS-IP address of the subscriber that was assigned
when the Acct-start message was created. If there is no NAS-IP-Address available, the peer IP address is considered as
the NAS-IP-Address for the session. IPSG terminates the subscriber sessions having the same NAS-IP-Address attribute
from which the Accounting On/Off message originated.
