Zero One Tech AF420B Router Open Port Instructions

Zero One Tech AF420B 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 Zero One Tech AF420B router.
  3. Navigate to the port forwarding section.
    • Click the Advanced Setup link.
    • Click the Local Server button.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Zero One Tech AF420B 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 Zero One Tech AF420B 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 Zero One Tech AF420B 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 Zero One Tech AF420B Router Username is: UNKNOWN
  • The Default Zero One Tech AF420B Router Password is: UNKNOWN

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:

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

Enter the port to forward into both the External Port No and the Internal Port No boxes.

Enter the IP address to forward these ports to into the Physical IP Address box. If you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box.

When you are done click the Add button.

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