Radrelay

I found FreeRadius 2.1.1 very easy to setup for authentication however, I am experiencing problems in setting up the accounting with 2 servers. Radrelay was very simple and although I have found lots of information on the radrelay function built in to FreeRadius, I have not been able to get it working. Is there a shortcut, Howto or instructions on what files need to be changed to get the detail files to match on 2 servers? Thanks Larry Reeves lreeves@heartoftn.net
