Port Forward Panel

Normally, incoming traffic (from the Internet) is blocked. However, port forwarding
lets you forward incoming traffic to specific ports and devices (per their local IP
address) on your network. For example, you can configure port forwarding so
that:

•

You can access your Remote Desktop from the Internet (by specifying the
WAN [public] IP address that the device is using).

•

Internet users can access a Web, FTP, or email server, or gaming or Internet
application hosted by your computer.

Note: Port forwarding creates a security risk. When not required, port forwarding should
be disabled.
Port forwarding does not apply to normal browsing, file downloading, running most online
games or other applications hosted on the Internet. (Some online games require port
forwarding.)

Before you can use or configure port forwarding, you must enable it. See

"Enabling Port Forwarding" on page 99

From the

Port Forward

panel of the

Router

tab of the

Advanced Settings

window, you

can:

•

Enable port forwarding for an application. See
