Port Forwarding on a Vigor2100 Series Router (V2.6.1)


This guide will walk you through the steps of port forwarding on the Vigor2100 series Firmware V2.6.1(5) router.

Step 1: Open up your favorite browser and go to the router’s default gateway address.

  • http://192.168.1.1 (Default Address)

Step 2: Login to the router.

  • Default Username: admin
  • Default password: admin (or blank)

Step 3: Once you have logged in go to “NAT” then click “Open Ports”.

Step 4: Be sure to check “Enable Open Ports”, “Comment” choose a name for the service (small description eg. web, camera, xbox, etc..). “Local Computer” is the Internal IP address that you want the port to be open on. Be sure to set “Protocols” to “1.” “TCP” and “2.” “UDP”. “Start Port” is the port you wish to open and “End Port” is the port you wish it to end at. Click “OK”.

Port Forwarding on a Vigor Router

Once you save the settings you should now be able to test your port at www.portchecktool.com. Please keep in mind your ISP (Internet Service Provider) can be blocking certain ports such as port 80, 25 and 21. You can call and ask if they are. If you are still not able to see the ports check your firewall and anti-virus software on your computer.

Here is an example. You have a webcam that has the IP address 192.168.1.100 and it runs on port 80. You want to be able to access this camera from outside your network on port 8080. You would enter the below values into port forwarding page.

  • Enabled Open Ports = checked
  • Local Computer = 192.168.1.100
  • 1. = Protocol set to “TCP”, Start port set to “8080” End port Set to “8080”
  • 2. = Protocol set to “UDP”, Start port set to “8080” End port Set to “8080”
  • Click OK to complete the setup

Then to view the camera you would use your No-IP host of “somehost.no-ip.com” like this:  http://somehost.no-ip.com:8080 to reach the webcam.
