How to Open Ports in a FRITZ BOX Fon WLAN 7570 Router

AVM FRITZ_Box_Fon_WLAN_7570 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 FRITZ BOX Fon WLAN 7570 router.
  3. Navigate to the port forwarding section.
    • Click the Settings button.
    • Click on Advanced Settings.
    • Click the Internet link.
    • Click on Permit Access.
    • Click the New Port Forwarding button.
    • Select Other Applications in the drop down.
  4. Create a port forward entry.

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:

Put a checkmark in the Enable checkbox.

Put a name for this forward in the Name box so that you can remember why you set this forward up. The name does not matter so pick something that has meaning to you.

The protocol that you want to forward is selected from the Protocol box.

If you are just forwarding a single port number then you can simply enter that same number into both the From Port, To Port and the Through Port boxes. If you are forwarding a range of ports, usually separated by a hyphen, then you need to enter the lowest number of that range into the From Port, To Port box and then enter highest number into the Through Port box.

The To Computer box contains a list of device names that are visible on your network. Choose a device from this box to forward ports to.

Click the Ok button when you are done.

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