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 Wireless 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
Wireless 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 192.168.1.10/80, then all HTTP requests from outside users will be
transferred to 192.168.1.10 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.
