Different IP addresses from home radius server

[Greg Rutz]

We are using FreeRadius 2.1.12 as a proxy to a remote radius server.  
The remote server (not under our direct control) receives RADIUS request 
messages on one IP address, but sends the response out a different 
interface (and thus has a diffferent IP). FreeRadius is rejecting the 
response since the IP does not match that of the request.  Is there a 
way to configure FreeRadius to allow this?
