Справочник Пользователя для Netopia R3100

Network Address Translation works by remapping the source IP address of traffic from the LAN to a single static 
or dynamically assigned IP address shown to the remote side of the router.

The feature can be implemented on a per Connection Profile basis. The network router can use two or more 
Connection Profiles simultaneously to connect to two or more networks. Each profile may have Network Address 
Translation enabled.

When Network Address Translation is enabled, the Netopia R3100 can either use a statically assigned IP 
address, or one dynamically assigned each time the router connects to the ISP. While a dynamically assigned IP 
address offers the ISP more flexibility, it does have an impor tant limitation. The router will require a static IP 
address to suppor t Web, FTP, or other ser vices available to the WAN. To suppor t these ser vices with Network 
Address Translation enabled, a ser vice can only be associated with one machine on the LAN. 

When connected to the Internet or some other large network using Network Address Translation, the individual 
machines on your LAN are not directly accessible from the WAN. Network Address Translation provides an 
inherently secure method of connection to the outside world.
