Forward L2TP request to another LNS

Hi All, I need to forward L2TP requests from Freeradius to another LNS. To explain in more details Two Domain xyz.com and abc.com are the realms for which I am accepting the connections and both are terminating on our LNS1. Forwarded to Radius.

From freeradius I want to forward the requests for xyz.com to LNS2 via Tunnel not via Realmproxy.

Is it possible ? If yes please can somebody throw some light on that. I am using Mysql with Freeradius. Thanks hemant
