NAT - Virtual Server
If you configure the Router as a virtual server, remote users who are 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 address. In other words, depending on the requested service (TCP/UDP port number), the Router
redirects the external service requests to the appropriate servers.
For example:
If a local PC with a private IP address of 192.168.62.50 acts as a Web and FTP server, configure the port to
forward HTTP (port 80) and FTP (port 21) to local address 192.168.62.50.

In order for a remote user to access this server from the Internet, the remote user must know the Router’s
WAN IP address that has been assigned by your ISP. If this address is 210.61.49.227, for example, an
Internet user can access this Web server by directing the browser to http://210.61.49.227.
The Router’s WAN IP address can be found in Status screen.

Firewall Setting
The Router provides extensive firewall protection by restricting connection parameters to limit the risk of
intrusion and defending against a wide array of common hacker attacks. Check the box next to “Disable” to
disable extensive firewall protection.
Note: The default setting is Enable.
