Trendnet TW100-S4W1CA 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 Trendnet TW100-S4W1CA router.
  3. Navigate to the port forwarding section.
    • Click the Advanced Setup button.
    • Click the Virtual Server link.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Trendnet TW100-S4W1CA 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.

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 Trendnet TW100-S4W1CA 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:

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:

Enable the By Port radio button.

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.

Put a dot into the Single or Range radio button.

If you are forwarding a single port, enter that port number into the Left Port Number and the Right Port Number boxes. If you are forwarding a range of ports, enter the lowest number of that range into the Left Port Number box. Then enter the highest number of that range into the Right Port Number box.

You need to enter the IP address that you are forwarding ports to in the Local Server 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.

When you are finished, click the Add button.

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