Port Forwarding and Port Triggering

Linksys EA-Series

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:
1.  
Make sure that the software you want to use has been installed onto a 

networked computer.

2.  Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-

Fi” on page 7.

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 34).

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 TCPUDP, or Both (default).
11. 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. 

The rest of the IP address has already been completed for you. 

12. Select Enabled, then click Save. If you don’t want to use port forwarding 

but want to keep the information in the table, unselect 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

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.
