Port Forwarding
Your device has built in advanced Security features that protect your network by
blocking unwanted trafc 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 conguration. You only need to edit
the conguration if you wish to do one or both of the following:
allow Internet users to browse the user pages on your local network (for ex-•
ample, by providing an FTP or HTTP server)
play certain games which require accessibility from the Internet•
This chapter describes how to congure Security to suit the needs of your net-
work.
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 PortForwarding.
Conguring Port Forwarding
Certain network games, chat or le 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, ac-
cess to them is disabled.
