Fastest Trendnet GS8100 Router Open Port Instructions

Trendnet GS8100 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 GS8100 router.
  3. Navigate to the port forwarding section.
    • Click the Services button.
    • Select NAT Rule Entry in the drop down.
    • Click the Add button.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Trendnet GS8100 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.

When you use Network Utilities you get your port forwarded right now!

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 Trendnet GS8100 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:


192.168.1.254

In the picture above the address bar has 192.168.1.254 in it. Just replace all of that with the IP address of your Trendnet GS8100 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: 192.168.1.254

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

Trendnet GS8100

You should see a box prompting you for your username and password.

  • The Default Trendnet GS8100 Router Username is: admin
  • The Default Trendnet GS8100 Router Password is: admin

Enter your username and password, and then click the Login button to log in to your Trendnet GS8100 router.

Trendnet Usernames and Passwords

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

If you still can't login to your router because you forgot your Trendnet GS8100 router username and password, use our How to Reset a Router Password guide to set your Trendnet GS8100 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:

Trendnet GS8100

Click the Services button near the top of the page.

Trendnet GS8100

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:

Use the Rule Flavor dropdown box to choose RDR.

Put a number that has not yet been in the Rule ID box.

Verify that IF Name is set to All.

From the Protocol box select the protocol for the ports that you want to forward.

Enter the IP address to forward these ports to into the Local Address From and Local Address To 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.

The default for Global Address From and Global Address To is set to 192.168.1.254. Leave it like this.

You can leave Destination Port From, Destination Port To and Local Port set to Any Other Port.

If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Local Port box and the highest number of that range into the Destination Port From box. If you are only forwarding a single port number then enter that number into both the Local Port and the Destination Port From boxes.

After you are done click the Submit button.
