Arris TG862G Router Port Forwarding Guide

All Arris TG862G router have a basic firewall that will help protect your home network from any unwanted access from the Internet. This firewall blocks incoming connections that you may want unblocked for a game or application. To unblock a connection you need to create a port forward. A port forward forwards a port through the firewall and directs it to a device on your home network.

To open a port you need to:

Setup a static IP address on the device you are forwarding these ports to.
Login to your Arris TG862G router.
Navigate to the port forwarding section.
- Click the Advanced link.
- Click on Port Forwarding.
- Click the Add Service button.
Create a port forward.

In this guide we will walk you through each of the above steps in detail.

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.

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 Static IP Setter will set up a static IP address for you.
Another way to get a permanent IP address is to set up a DHCP reservation.
Or, manually create a static ip address with our Static IP Guides.

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.

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.

Step 2

You need to use a web browser (Chrome, Edge, Firefox, Internet Explorer) to login to the Arris TG862G router's web interface. It doesn't matter which web browser you use to do this, merely pick your favorite.

After opening up the web browser look for the address bar. This is normally at the top of the page like this:

Image of a browser address bar — Browser address bar

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 Arris TG862G IP Address is: 10.0.0.1

Enter the appropriate IP address in the address bar and click the Enter key on your keyboard. If everything goes as it should you will see the following page:

Do you see the Login screen? This is where you want to be.

The Default Arris TG862G Router Username is: admin
The Default Arris TG862G Router Password is: password

Simply enter the username and password and click the LOGIN button to access the Arris TG862G web interface.

Having Trouble Logging In?

This is where most of us will get stuck. Here are a few things you can try:

Try other Default Arris Router Passwords. Sometimes a router will update the firmware and change the username and password.

Crack your router's password. Use our Find Password App. It automates the process of trying a bunch of different combinations. To prevent illegal activity this can ONLY be used on your home network. It can not be used over the Internet. Learn more in our Router Password Cracker.

Finally, if none of the other options work, it may be time for a reset. A factory reset will erase every single setting you have ever changed on the device. We highly recommend exhausting other options before resorting to a reset. Learn more about resetting this router on our Reset the Arris TG862G router page.

Step 3

Now let's find the port forwarding section of the router. To do this we start on the following page of your Arris TG862G router:

Click the Advanced option in the left sidebar.

Below that, click the option of Port Forwarding

Now click the Add Service button on the right side of the page.

In the Services Name dropdown box choose Other.

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 required protocol for these ports from the Service Type dropdown box.

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

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

Click the Save button when you are all done.

Don't forget to SAVE after each entry.

Did Your Ports Open?

After you have finished forwarding the Arris TG862G router you need to test them to see if they forwarded correctly. In order to do this we recommend using our Open Port Checker. This is located in our free trial of the Network Utilities tool. Not only is this Open Port Checker free but it is the only online port checker that is guaranteed to work.
