How to set up port forwarding for multiple ports
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, 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:
1. Make sure that the software you want to use has been installed on a networked computer.
2. Log in to Linksys Smart Wi-Fi. (See ‘‘How to connect to Linksys Smart Wi-Fi’’ on page 10 .)
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
39 .)
4. Under
Router Settings
, click
Security
.
5. Click the
Apps and Gaming
tab.
6. Click Single Port Forwarding . The Single Port Forwarding screen opens.
7. Click Add a new Single Port Forwarding .
8. In the Application name field, enter a descriptive name.
9. Enter in the same port number for the External Port and the Internal Port .
10. In the
Protocol
drop-down list, select
TCP
,
UDP
, or
Both
(default).
11. In the
Device IP#
field, complete the IP address you have reserved for the computer you want
to forward Internet traffic to.
12. Select the Enabled checkbox, then click Save . If you don’t want to use port forwarding but
want to keep the information in the table, deselect the checkbox.
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
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.
