Hi

Anyone have a configuration sample for freeradius ?

Hi Oliver, You need to configure a RADIUS proxy to do this. I haven't got that far yet, it's next on my list of things to lab. I've recently lab'ed the stage before hand which is for a working LAC. The LAC takes in PPP requests, queries a RADIUS server based on incoming auth domain name, the RADIUS server returns the LNS/tunnel end point details for that domain, the LAC established an L2TP tunnel to the LNS returned from RADIUS and then the LNS makes a final auth against the RADIUS server. In my lab I used the same RADIUS server for both the LAC and LNS as I wanted to work out the config required for the LAC. My next lab excerise to work out the RADIUS config required to have seperate RADIUS servers and have the LAC RADIUS server proxy requests to other RADIUS servers based on a list of domain names. I guess that is what you want. This might give you some insight though; http://null.53bits.co.uk/index.php?page=lac-wholesale-pppoa-e-l2tp-tunnellin... Cheers, James.
