the Router shares the single IP address assigned by your ISP with the 
computers on your network. 
This function should only be disabled by advanced users, and if your

advanced system configuration. If you have a single IP address and 
you turn NAT off, the computers on your network will not be able to 
access the Internet. Other problems may also occur....
