Hi,
I need to configure the Free Radius (as proxy) to forward the authentication request to safeword and RSA Servers from AT & T VPN Users based on user@norealm and user@realm condition.
 
Users - VPN - Free Radius - Safeword & RSA

Example:
User - VPN - Free Radius (no realm, so nostrip) and pass the authentication to safeword servers.
User@ab.abc.com - VPN - Free Radius (strip realm name) and pass the authentication to RSA servers.
 
How do I configure the Free Radius as a proxy to achieve this.
 
Also I need to configure 2 FreeRadius (as proxy) Server to achive High Availability, can I configure the same on both the servers.
 
If the above is not possible can I use an NPS Radius Proxy to achive this, but in this case where s! hould I place the FreeRadius, between VPN and NPS or between NPS and safeword. My Safeword does not support EAP, so I cannot achieve this by NPS Radius proxy directly forwarding request to safeword.

Thank you in advance.
