Did you know your Technicolor TC8715D router has a firewall? The firewall helps protect your home network from unwanted Internet access. The firewall blocks all unauthorized ports or connections to your home network. Some online games and programs will run much smoother if you have additional ports opened. This process of opening additional ports is called a port forward.

In this guide I will show you exactly how to forward ports on the Technicolor TC8715D router. I will explain how to:

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.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

TIP: I recommend writing this static IP address down. You need it a little later in the port forwarding process.

Step 2

Now that you have set up a static IP address on the device you plan on forwarding these ports to it is time to login to the Technicolor TC8715D router.

The first step is to open up a web browser such as Internet Explorer, Chrome, Edge, or Firefox. It normally doesn't matter which browser you use, I recommend using one you are familiar with.

Once you have opened the web browser, find the address bar. The address bar is found at the top of the page 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 TC8715D IP Address is:

Simply press the Enter key after you have entered the router's IP address into the address bar. If the correct IP address was used you will see a login screen like this:

Technicolor TC8715D Login
Technicolor TC8715D Login.

If you do not see a page like the one above, you need to find out what the router's IP address is. To do this use our How To Find Your Router's IP Address page.

Enter the router username and password in the spaces provided.

Having Trouble?

A lot of people get stuck at this point. Most router setup procedures ask you to change the username and password before continuing. These passwords get lost, and logging into the router interface becomes a challenge. Here are a few things you can try before tossing the router out the nearest window:

  • It is possible we don't have the most current default username and password. Every once in a while router manufactures change the defaults on us to keep us on our toes. Here is a list of all the different default usernames and passwords Technicolor has ever used: Default Technicolor Router Passwords.
  • None of the defaults worked? Most likely you changed the password and have forgotten it. If you can't guess what you changed it to, let us help. Use our Find Password App. It does the guessing for you.
  • Are you still stuck? It is probably time to consider a factory reset for your Technicolor TC8715D router. To do this follow the procedure explained on our How to Reset a Router page.

Step 3

You should now be logged in and looking at the At a Glance page of the Technicolor TC8715D router interface. It will look like this:

Technicolor TC8715D At a Glance

Select the Advanced link in the left sidebar.

Technicolor TC8715D Port Forwarding.

This should take you to the page above. If not, simply click the Port Forwarding option in the left sidebar.

Now, click the yellow +Add Service button in the center section of the page.

Congratulations, you have found the port forwarding page.

Choose Other from the Common Services dropdown box.

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

Select the protocol type of the ports you are forwarding from the Service Type box.

Enter the IP address to forward these ports to into the Server IPv4 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.

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

Click the Add button when you are finished.

Don't forget to click the yellow Add button after each entry.

Check your Ports

Sometimes it can be difficult to tell if the ports forwarded properly, so we recommend using our Open Port Checker to see if the ports forwarded correctly. Our port checker uses a local application to see if the server is listening. This guarantees an accurate result.
