NAT
Network Address Translation allows multiple users to access the 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 Router 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 Router 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.

Special Applications
Some applications require multiple
connections, such as Internet gaming,
video-conferencing, and Internet
telephony. These applications may
not work when Network Address
Translation (NAT) is enabled. If you
need to run applications that require multiple connections, use these pages
to specify the additional public ports to be opened for each application.
