Proxy EAP-TTLS inner auth type

[Sayantan Bhowmick]

Hi,
   I was tryin to figure out if it is possible to proxy only
the inner auth type of EAP-TTLS. The only information I could
find on this is:

http://lists.cistron.nl/pipermail/freeradius-users/2005-March/042098.html

This talks about PEAP. Is the same possible for EAP-TTLS?

Also i could not find any information about the attribute 
"proxy_tunnel_request_as_eap" mentioned in the previous mail. 
Can someone please point me to any documentation on how to 
configure the server to terminate the tunnel and proxy the 
inner auth type.

Thanks in advance.
