Virtual Server

Your device has built in advanced Security features that protect
your network by blocking unwanted traffic from the Internet.

If you simply want to connect from your local network to the
Internet, you do not need to make any changes to the default
Security configuration. You only need to edit the configuration if
you wish to do one or both of the following:

 allow Internet users to browse the user pages on your local

network (for example, by providing an FTP or HTTP server)

 play certain games which require accessibility from the

Internet

This chapter describes how to configure Security to suit the
needs of your network.

By default, the IP addresses of your LAN PCs are hidden from
the Internet. All data sent from your LAN PCs to a PC on the
Internet appears to come from the IP address of your device.

In this way, details about your LAN PCs remain private. This
security feature is called Port Forwarding.

Configuring Virtual Server

Certain network games, chat or file sharing software do not
work with your default Port Forwarding setting. Your device
knows the port, protocol and trigger information needed to allow
access to the common applications listed below, but by default,
access to them is disabled.
