Fastest Telstra Ultimate AC753S Router Port Forwarding Guide

Telstra Ultimate_AC753S 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 Telstra Ultimate AC753S router.
  3. Navigate to the port forwarding section.
    • Click the Advanced settings link.
    • Click the Router link.
    • Click on Port Forward.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Telstra Ultimate_AC753S 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 Telstra Ultimate_AC753S 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:


In the picture above the address bar has http://ultimate.telstra in it. Just replace all of that with the IP address of your Telstra Ultimate_AC753S 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: http://ultimate.telstra

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

Telstra Ultimate_AC753S

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

  • The Default Telstra Ultimate AC753S Router Username is: NONE

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:

Create a name for this forward and put it in the Name box. The name is only used as a reminder and has no effect on the port forward.

Enter the IP address of the device that you want to forward ports to into the IP box. This can be either the IP address of your computer or the IP address of another device on your network.

Enter the port to forward into the Port box.

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

When you are all done click the Save button.

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