acts as a Dynamic Authorization Server (DAS). If the same request must be forwarded
to another AAA entity, the proxy acts as a DAC.
Requests are sent based on the configuration. For example, using advanced policy, you
can configure on the basis of user-realm or target NAS. The proxy HP-UX AAA Server
listens to Disconnect and CoA requests on a port that can be configured. The
configuration settings of this port are the same as that of authentication and accounting
proxy ports. The default port is 3799.
Figure 20-14 illustrates the Dynamic Authorization proxy functionality.

Configuring for Dynamic Authorization Proxy Functionality
To configure the HP-UX AAA Server for Dynamic Authorization proxy functionality,
you must configure the routing tables for the requests in the /etc/opt/aaa/
proxy-egress.grp proxy egress policy file.
You can configure the routing tables on the basis of attributes, such as user's realm and
target NAS (authenticator), in the incoming request.
Configuring on the Basis of User's Realm
To configure routing tables based on the user's realm, add the following lines in the
/etc/opt/aaa/proxy-egress.grp file:
if( Interlink-Packet-Code = "Disconnect-Request" ||
Interlink-Packet-Code = "COA-Request" )
