Router Port Forwarding and Port Triggering
How to port forward:
How to port forward a wireless router is a very simple process once you understand what it is.
Port forwarding is done by adding an entry into your wireless routers configuration.
This entry assigns specific ports on the router to be directed to a particular computer by its IP address on the local network.
You might ask why are router port forwards necessary for remote computers across the Internet to connect directly with a specific computer on a private or local network.
Well instead of the wireless router broadcasting the remote servers network packets to every IP address on your local network, slowing it to a crawl.
It simply uses port forward to direct all the heavy traffic only to the computer requesting it.
The different ways of forwarding:
When learning how to port forward it’s important to know the different types of forwarding your router can perform.
Applications use different ports in the router to gain access through the firewall to perform unique and proprietary functions.
These proprietary functions allow applications to communicate and work with front and back end operations on both sides of the firewall, while maintaining network security throughout the private network by performing stateful packet inspection.
Before we start there 3 common methods of router port forward used by most high performance wireless router in the market today, so We’ll be describing the differences between them.
The first type of forward is called single port forward:
Single port forwarding is mostly used for routing all service specific network traffic on your local area network to be directed to a specific computer.
This type of how to port forward would be ideal for an internal e-mail server that would take all network packets for the POP3 and SMTP services and forward them to an e-mail server on your local network to be processed, and distributed.
The next type is called port range forwarding:
Port range forwarding is allows the router to not only forward one specific port, but can specify a range of ports to be directed to a specific IP address.
This type of forwarding could also be used for an e-mail server as well as FTP and web servers, but is becoming more widely used in the online gaming industry, because so many online game hosting servers require multiple ports or port ranges be used for the service to operate.
The last type is called port range triggering:
Port range triggering operates slightly different than the previous two methods in that the specified port range that’s being forwarded is directed back to the IP address of the computer on the local network that has sent network packets out the specified trigger ports.
Now that we’ve gone over the different types of how to port forward, I’m going to demonstrate how to setup port range forwarding for the use of playing “Call of Duty” on a wireless home network.
How To Port Forward
Let’s get started:
In this example I’ll be demonstrating how to port forward using a Linksys E4200 series wireless router.
When setting up port range forwarding for online gaming, the router configuration menu will require the internal network IP address of the computer that it will be forwarding to.
It would be best if the IP was a “Static IP” so that port forwarding information remains accurately assigned to the correct computer on the network.
- On your computer click on: Start\All Programs\Accessories\Command Prompt
This will open your computers command prompt window displaying your current path followed by a blinking cursor.
- Type in the following command: “ipconfig /all” and press the “Enter” key.
Detailed information about your computers IP address configuration will return in the command prompt.
- Look for the “IPv4 Address”, and write it down so we can enter it in the steps ahead.
This is your computers IP address on your wireless home network.
If you need instruction on accessing your wireless routers configuration menus or are unfamiliar with the process, we provide step by step instructions for a few of the top manufactures of wireless enabled routers on the market today.

- Once you have logged into your routers configuration menu program, locate and click on the “Applications & Gaming” tab, and then on the “Port Range Forwarding” sub tab.
This will display the “Port Range Forwarding” applet screen, where we’ll be entering our port range, protocol and forwarding IP address information.
- For the ever popular online game “Call of Duty” we’ll Enter in the following port and protocol information in the E4200 router table.
Call of Duty TCP Ports: 28960 UDP Ports: 20500, 20510, 28960
- The use of the “Application Name” field is used just as a reference to which application the port range is being assigned for, and has no operational purpose.
- In the “To IP Address” field, Enter the IP address from the computer that will be playing Call of Duty online.
After entering all the field data your screen should look as follows, with the exception of the IP address being that of one on your wireless home network.
- At the bottom of the page Click on the “Save Settings” button.
- After the settings have been saved, Close out the web browser.
That’s it! You may now enjoy playing Call of Duty online gaming against players from around the world.
