How to set up port forwarding for multiple ports
Why would I set up port forwarding for multiple ports? Port forwarding is
a feature that forwards inbound traffic from the Internet on a specific port to
a single device on your local network Unlike a web camera that typically only
requires a single port to be forwarded, some applications require forwarding
of multiple ports VNC (Virtual Network Computing) software that allows you to
operate your computer remotely from anywhere on the Internet is an example
of an application that requires multiple ports to be forwarded To forward to
multiple ports, just create additional entries to forward additional ports to the
same IP address
Example: You want to set up your computer so you can remotely access it using
VNC software By default, VNC uses TCP ports 5800 and 5900
To set up single port forwarding for multiple ports:
Applications & Gaming > Single Port Forwarding
1. Make sure that the software you want to use has been installed onto a
networked computer
2. Log into the browser-based utility (see "How to open the browser-based
utility" on page 21)
3. Set up DHCP reservation for the IP address of the computer on which
you installed the software (See "How to set up the DHCP server on your
router" on page 24)
4. Click the Applications & Gaming tab, then click the Single Port
Forwarding page
5. For each entry, enter a descriptive name in the Application Name field
6. For each entry, enter in the same port number for the External Port and
the Internal Port
7. 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
Port Forwarding and Port Triggering
8. Select Enabled next to the IP Address field
9. Click Save Changes at the bottom of the screen
NOTE
If you want to use software such as VNC on multiple computers,
you will need to reconfigure the default ports that VNC uses on
each additional computer Then, create additional port forwarding
entries for each additional computer See your software's
documentation for help
How to set up port forwarding for a range of ports
Why would I set up port forwarding for a range of ports? Port forwarding is
a feature that forwards inbound traffic from the Internet on a range of ports to
a single device on your local network Unlike a web camera that typically only
requires a single port to be forwarded, some applications require forwarding
to a range of ports
Example: You want to set up your computer so you can use BitTorrent, a
popular peer-to-peer file sharing application BitTorrent uses port 6881 by
default If that port is busy, the requesting BitTorrent client tries the next port
in sequence The most common configuration for home routers with a single
BitTorrent computer is to set up port forwarding using a range of ports starting
with 6881 and ending with port 6889
