ZTE ZXDSL 831 routers include a very basic firewall that helps protect your home network from 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.
In this guide we will walk you through the steps to getting your ports forwarded on the ZTE ZXDSL 831 router. These steps include:
- How to setup a static IP address on the device you plan on forwarding these ports to.
- How to login to the **ZTE ZXDSL 831 ** router web interface.
- How to find the port forwarding page in the router's web interface.
- How to setup a port forward for the online game or program of your choice.
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!
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.
TIP: Write this static IP address down. You need it in Step 4.
Now we are going to login to your ZTE ZXDSL 831 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:
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.

Pick the Customized Service radio button choice.
Enter the name of the program into the Customized Service box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded is be a good idea.
The protocol that you want to forward is selected from the Protocol box.
If you are only forwarding a single port then you can enter that same port number into the External port start, External port end, Internal port start and Internal port end boxes. If you are forwarding a range of ports then you need to enter the lowest number of the range into the External port start and Internal port start boxes and the highest number of the range into the External port end and Internal port end boxes.
Enter the IP address that you want to forward these ports to in the Internal server IP address box. You can enter either the IP address of your computer or the IP address of another computer or device on your network.
Click the Apply button when you are done.
Don't forget to click the Apply button when you are finished with each entry.
