How to set up port forwarding
For
ALL
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 58)
•
A range of ports (see “How to set up port forwarding for a range of ports”
on page 58)
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 .
To set up single port forwarding:
Applications & Gaming > 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 29) .
2. Log into the browser-based utility (see “How to open the browser-based
utility” on page 25) .
3. Click the Applications & Gaming tab, then click the Single Port
Forwarding page .
4.
Select the type of application from the
Application name
drop-down
list . One of the more common types to select is
HTTP
, but see your
device’s documentation for recommendations .
5. In the To IP Address field, enter the last three digits of the IP address you
have reserved for the computer you want to forward Internet traffic to .
The rest of the IP address has already been completed for you .
6.
Select
Enabled
next to the IP Address field .
7. Click Save Changes at the bottom of the screen .
TIP
For other devices not included in the Application Name drop-
down list, see the device’s documentation for port and protocol
information .
