Proxying without a realm

[Jeff Fern]

Hello all,

I have got an Airespace wireless lan system that allows multiple WLANs to
be created and appear as completely seperate networks. The system allows
radius authentication via multiple servers, but it does not allow
specifying certain WLANs to certain servers.

To determin which WLAN has been connected to, airespace passes an
attribute along with the username (MAC Address), it does not pass any
realm information.

Does anyone know if it is possible to configure freeradius to proxy out
all incoming radius requests but convert the attribute to an actual realm?

To provide a bit more background detail, we have a Tatara AAA system which
is connected to a HLR (the HLR actually does the authentication, Tatara
just acts as a proxy to it). I need to create two seperate WLANs which,
when presented to Tatara for authentication, one will appear as a home
connection and the other as a roaming connection - hence the need for
specific realms.

Freeradius would be proxying all requests to the same Tatara system (but
needs to add realm information).

Any help or advise would be gratefully recieved.

Regards,
