Port Forwarding popular ports in a Linksys Router

Introduction

Here we will show you how to forward popular ports 80 and 1024 TCP to a Static LAN IP of 192.168.1.200. Port 80 and 1024 are often used for popular devices from Linksys such as IP Cameras, Network Storage Devices and other popular products such as the Cisco MediaHub

Requirements

A Linksys Router and you must also have your Internet Server or device set to a Static LAN IP address of 192.168.1.200
  1. 1Log Into your Router

    Log into your router, typically it will be at 192.168.1.1 and the default username is blank with admin as the password.
    Once you log into the router, Find and Click the APPLICATIONS & GAMING link in the top menu as shown circled in the screenshot below. Your router may look slightly different, but most Linksys routers now have all port forwarding within the Applications & Gaming menu.
  2. 2Applications and Gaming Menu

    Once you get into the APPLICATIONS & GAMING menu in the router, you will see a list of ports, and IP's as shown in the screenshots below. Keep in mind that your router will look like one of the two screenshots. Newer routers will look like the first screenshot, and older models appear similar to the second screenshot.
    Adding Ports into the Applications and Gaming Menu in the Linksys Router
    A) Newer Linksys Routers - If your Applications and Gaming screen looks similar to the one below, WEB is already pre-defined in the drop down list of ports. You should set yours to look like the screenshot below. Select WEB from the dropdown list of applications, then select TCP, Set the LAN IP to 192.168.1.200 and Enable should be checked on. Lastly, you should also add port 1024 if your ISP blocks port 80, you won't have to add another port, you just change the port on the Camera.
    In the Applications and Gaming menu, add in the "WEB1024" name within the Application field exactly as shown below. Then add in the Start port of 1024, End port is 1024, TCP or Both for protocol (either will work) and make sure the IP address is set to the Static LAN IP of the device we set earlier. In this case, we used 192.168.1.200. Now make sure the port range is enabled.
    Scroll down and click SAVE SETTINGS to save these settings. You are now done with the port forwarding. Double check your settings before moving to the next step.
  3. 3Testing your Device

    That's it! You are now ready to test and make sure that the server, network device or camera is running properly and answering HTTP requests over the Internet. This means you must leave the network where the server, network device or camera is located to test over the WAN (Internet). Testing the domain name from the same location as the server, network device or camera will NOT work in many cases, depending on the router. We urge you to use the DOMAIN NAME when you are away from the location where the device resides, and when on the same network, use the INTERNAL IP ADDRESS; in this case 192.168.1.200
    Connecting Remotely to your Camera over the Internet:
    If your camera is located at your home, go to work and test this step, or go to a friends house with a broadband connection and test from there. If the Camera is at work, do your final tests from home, etc.
    Connect a laptop or desktop to the Internet and the run a web browser on that system. You will now need to type in the DOMAIN NAME you are using when you signed up with TZO. See the screenshot shown below for an example.
