Simple Instructions to Help Setup a Port Forward on the BT Voyager 2100 Router

BT Voyager2100 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 BT Voyager 2100 router.
3. Navigate to the port forwarding section.
   • Click the Advanced link.
   • Click the Configuration link.
   • Click on Virtual Server.
   • Click the Port Forwarding link.
   • Click the Add button.
   • Click the User Defined radio button.
4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your BT Voyager2100 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.

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 Static IP Setter will set up a static IP address for you.
• Another way to get a permanent IP address is to set up a DHCP reservation.
• Or, manually create a static ip address with our Static IP Guides.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

Step 2

Now we are going to login to your BT Voyager2100 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:

Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.

The default BT Voyager 2100 IP Address is: 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 BT Voyager 2100 Router Username is: admin
• The Default BT Voyager 2100 Router Password is: admin

Enter your username and password, and then click the Login button to log in to your BT Voyager2100 router.

BT Usernames and Passwords

If your username and password do not work then please visit our Default BT Router Passwords page.

If you still can't login to your router because you forgot your BT Voyager2100 router username and password, use our How to Reset a Router Password guide to set your BT Voyager2100 router back to its factory settings.

Step 3

Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:

Click the Advanced link near the left of the page.

Click the Configuration link near the left of the page.

You should now see a new menu. In this new menu, click Virtual Server.

Click the Port Forwarding link near the top of the page.

Click the Add button near the right of the page.

Put a dot into the User Defined radio button.

Step 4

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:

• Browsing our List of Games
• Check out our our List of Games by Genre
• See our List of all Applications

You need to name this entry in the User Defined box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward.

The default for From Internet Host IP is set to ALL. Leave it like this.

You need to enter the IP address that you are forwarding ports to in the Forward to Internal Host IP Address 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.

In the Protocol box select the protocol that you want to forward these ports over.

If you are forwarding a range of ports then you need to enter the lowest number of the range into the External Packet Port Start and Internal Host Port Start boxes and the highest number of the range into the External Packet Port End and Internal Host Port End boxes. If you are only forwarding a single port then you can enter that same port number into the External Packet Port Start, External Packet Port End, Internal Host Port Start and Internal Host Port End boxes.

When you're finished, click Apply near the bottom of the screen to save your changes.

Test if Your Ports are Open

Now that you have forwarded ports on the BT Voyager2100 you should test to see if your ports are forwarded correctly.

To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.
