How to set up port forwarding
Why would I use port forwarding? Port forwarding is a feature that forwards
inbound traffic from the Internet on a specific port or ports to a specific device
or port on your local network. You can set up port forwarding for:
• A single port (see “How to set up port forwarding for a single port” below)
• Multiple ports (see “How to set up port forwarding for multiple ports” on
page 52)
• A range of ports (see “How to set up port forwarding for a range of ports”
on page 52)
How to set up port forwarding for a single port
Why would I use port forwarding for a single port? Single port forwarding
is a feature that forwards inbound traffic from the Internet on a specific port to
a single device on your local network. An example of single port forwarding
would be to forward inbound web requests, typically on port 80, to a web
server.
TIP
See the device’s documentation for port and protocol information.
To set up single port forwarding:
1.
Follow your device’s instructions for configuring it with a static IP address
or use DHCP reservation to assign it a permanent address (see “How to
set up the DHCP server on your router” on page 38).

In the Device IP# field, enter the last three digits of the IP address you
have reserved for the computer you want to forward Internet traffic to.
