Hello Nayeem -

I will need to see a copy of your configuration file and a trace 4  
debug showing what is happening.

It is difficult to imagine how a user can get connected, but without  
an IP address. What are the exact symtoms?

BTW - you can also define multiple IP address pools on most NAS  
equipment.

regards

Hugh
