Modifying AVPs when acting as a proxy

[Olli Salonen]

Hello,

I have a problem with my NAS and my current RADIUS server. The RADIUS
server is responding with 2 vendor-specific AVPs, which my NAS is not able
to understand. However, there are corresponding vendor-specific AVPs in my
NAS as well.

Could I install FreeRADIUS as a proxy between my current NAS and RADIUS
server and have it somehow modify the answer I get from my current RADIUS,
effectively acting as a translator between my two current nodes?

Cheers,
