load balancing 802.1x auth requests

[Alison Lee]

Hi,

We would like to load-balance 802.1X wireless authentications on 
multiple radius servers. The problem is that EAP methods require a 
series of requests and replies between the client and the same radius 
server, but a normal radius proxy will treat each request as a new one 
and forward them to different servers. With the latest release of 
FreeRADIUS, is it possible to keep states in the proxy server so that it 
can distinguish new requests from current outstanding requests?

Any suggestions/insights would be much appreciated.

Thanks,
