Looking at the source, I see that it can at least identify the packets, 
but then ignores them, because they are not authentication/accounting 
packets.

I dit a minor change, to not ignore the packet and pass it to the 
accounting module, but then the accounding module crashed.

As my C skills is non existant, I can only do "copy and paste" type 
programming.

I could attempt some changes with some pointers......
