Network Address Translation allows communication between the LAN connected to the Netopia R6000 Series 
and the Internet using a single IP address instead of a routed account with separate IP addresses for each 
computer on the network.

Network Address Translation also provides increased security by hiding the local IP addresses of the LAN 
connected to the Netopia R6000 Series from the outside world.

The setup is simpler, so ISPs typically offer Internet accounts suppor ting Network Address Translation at a 
significant cost savings.
