Did you know this Technicolor TC7210.dNZ router has a basic firewall to help protect your home network from unwanted access from the Internet. This process of blocking ports is what a firewall does. When you need one or more of these ports unblocked it is called a port forward.

In this guide we will be walking you through each step in the process of getting your ports forwarded for the Technicolor TC7210.dNZ router:

We will walk you through how to:

  1. Setup a static IP address on the device or game console you want these ports forwarded to.
  2. Login to your Technicolor TC7210.dNZ router.
  3. Find the port forwarding section.
    • Click the Advanced link.
    • Click on Forwarding.
    • Click the Create IPv4 button.
  4. Create a port forward.

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.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

NordVPN birthday deal!

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

Step 2

Now we are going to login to your Technicolor TC7210.dNZ router. This router has a web interface, so you need to login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Safari. It usually does not matter which browser you decide to use.

Open up your web browser and find the address bar. It should look something like this:

Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.

The default Technicolor TC7210.dNZ IP Address is:

At this point you should see the authentication box like this:

This box is asking for a password and username. Go ahead and enter the login values of your Technicolor TC7210.dNZ router.

Enter your username and password, and then click the OK button to login to your Technicolor TC7210.dNZ router.

Having Trouble?

This is an extremely common place to get stuck. If you find yourself here, there are several things you can do:

  • First, we recommend trying other default Technicolor usernames and passwords. Sometimes if you have a slightly different firmware version you may have a different username and password. Try these Default Technicolor Router Passwords.
  • If that does not work, it is probably because you changed the username and password in the past and have forgotten what you changed it to. If this is the case, use our Find Password App to help you figure out what you changed it to. This app automates the process of trying thousands of different combinations for you. Learn more about this on our Router Password Cracker page.
  • Finally if nothing else works, it might be time to consider a reset. A reset erases every thing you have ever changed on the device including the username and password for your router. We strongly recommend trying other troubleshooting methods first. Learn more on our How to Reset a Router page.

Step 3

This step involves finding the port forwarding section of your router. To do that let's start on the Status page of the device:

First, you are going to click the Advanced link at the top of the page.

Now, click the option in the left sidebar labeled Forwarding.

Enter the IP address that you want to forward these ports to into the Local IP Address box. Note that 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 instead.

If you are forwarding a range of ports then you need to enter the lowest number of the range into the Local Start Port and External Start Port boxes and the highest number of the range into the Local End Port and External End Port boxes. If you are only forwarding a single port then you can enter that same port number into the Local Start Port, Local End Port, External Start Port and External End Port boxes.

Select the required protocol for these ports from the Protocol dropdown box.

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

Use the Enabled dropdown box to pick On.

When you are done click the Apply button.

Make sure to click the Apply button after each entry.

That's it, you are finished.

Testing if Your Ports are Open

After a port forward you need to test them to be sure they forwarded successfully. In order to do this we recommend using our Open Port Checker found in our Network Utilities free trial. Our port checker uses a local application to listen for the server trying to connect. This way we can confirm whether your port is forwarded or not.
