Viking II AR520 Router Open Port Instructions

Viking II AR520 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

  1. Setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your Viking II AR520 router.
  3. Navigate to the port forwarding section.
    • Click the Services button.
    • Select NAT Rule Entry in the drop down.
    • Click the Add button.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Viking II AR520 router.



We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.

When you use Network Utilities you get your port forwarded right now!

Step 1

It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

  • Recommended - Our free program will setup a static IP address for you.
  • Or follow our Static IP Address guides to setup a static IP address.

After setting up a static ip address on your devices you need to login to your router.

Step 2

Now we are going to login to your Viking II AR520 router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.

Open up your web browser and find the address bar. It should look something like this:


192.168.1.1

In the picture above the address bar has 192.168.1.1 in it. Just replace all of that with the IP address of your Viking II AR520 router. Your router's IP address can also be refered to as your computer's default gateway.

By default the IP address is set to: 192.168.1.1

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

You should see a box prompting you for your username and password.

  • The Default Viking II AR520 Router Username is: root
  • The Default Viking II AR520 Router Password is: root

Enter your username and password, and then click the Login button to log in to your Viking II AR520 router.

If you still can't login to your router because you forgot your Viking II AR520 router username and password, use our How to Reset a Router Password guide to set your Viking II AR520 router back to its factory settings.

Here are the ports to forward for Xbox Live:

TCP Ports:3074
UDP Ports:3074

If you are looking for the ports for a different application you can find it by either:

From the Rule Flavor dropdown box choose RDR.

Pick a number that has not yet been used and put it into the Rule ID box.

Verify that IF Name is set to All.

Select the protocol type of the ports you are forwarding from the Protocol box.

You need to enter the IP address that you are forwarding ports to in the Local Address From and Local Address To box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.

Verify that Global Address From and Global Address To is set to 192.168.1.1.

Leave Destination Port From, Destination Port To and Local Port set to Any Other Port.

If you are forwarding a single port, enter that port number into the Local Port, Destination Port From and the Destination Port To boxes. If you are forwarding a range of ports, enter the lowest number of that range into the Local Port, Destination Port From box. Then enter the highest number of that range into the Destination Port To box.

Click the Submit button when you are all done.
