Hello Alex -

I would have expected your accounting start to contain the IP address  
for the session - you may have to set some configuration option in  
the equipment to have it do this.

Once you have the IP address in an accounting request, you can insert  
it in the online table directly.

If you send me a copy of your configuration file and a trace 4 debug  
showing the access request and the subsequent accounting requests, I  
will take a look.
