Network Address Translation allows multiple users to access the
Internet sharing one public IP.
Internet sharing one public IP.
Address Mapping
Allows one or more public IP addresses to be shared by multiple
internal users. This also hides the internal network for increased privacy
and security. Enter the Public IP address you wish to share into the
Global IP field. Enter a range of internal IPs that will share the global IP
into the "from" field.

Virtual Server
If you configure the ADSL Wireless Base Station as a virtual server,
remote users accessing services such as web or FTP at your local site
via public IP addresses can be automatically redirected to local servers
configured with private IP addresses. In other words, depending on the
requested service (TCP/UDP port number), the ADSL Wireless Base
Station redirects the external service request to the appropriate server
(located at another internal IP address).

For example, if you set Type/Public Port to TCP/80 (HTTP or web) and
the Private IP/Port to 192.168.2.2/80, then all HTTP requests from
outside users will be transferred to 192.168.2.2 on port 80. Therefore,
by just entering the IP address provided by the ISP, Internet users can
access the service they need at the local address to which you redirect
them.
