Opening Ports in a Topcom Xplorer 871 BT Router

Topcom Xplorer-871-BT 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 Topcom Xplorer 871 BT router.
  3. Navigate to the port forwarding section.
    • Click the Configuration button.
    • Click on Virtual Server.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Topcom Xplorer-871-BT router.

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 Topcom Xplorer-871-BT 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.

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:

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

Select the protocol type using the Port Type radio button. If you need both TCP and UDP then create a duplicate configuration.

The first configuration needs to have TCP selected while the second one has UDP selected.

Enter the IP address that you are forwarding ports to in the Host IP Address box. This is either the IP address of a computer or the IP address of another device on your network.

In the Private Port box enter the port to forward.

Click the Add This Setting button when you are finished.

Your ports should now be open. It is time to test them.

Test if Your Ports are Open

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.
