Your ZTE ZXDSL 831 router has a basic firewall that helps protect your network from unwanted Internet activity. This firewall blocks all incoming and outgoing connections from your network. Some online games and programs will run much smoother if you open additional connections. In order to open additional connections you need to create a port forward.
In this guide we will walk you through the port forwarding steps for the ZTE ZXDSL 831 router.
- 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.
It is important to set up 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. Download Network Utilities today!
- Another highly recommended way of getting a permanent IP address is to set up a DHCP Reservation.
- Or, follow our Static IP Address Setup guides.
With DHCP reservations you can manage your devices from your router. This centralizes the management of your network and helps prevent IP address conflicts. Using this method you do not have to log in to your devices separately.
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. Routers have 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 looks 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.
By default the IP address is set to: 192.168.1.1
After entering the IP address of your router you can simply press enter. If everything goes correctly you will see the login page:
If you do not see a login page or box, you should check if your router IP address have been changed. To do this, follow the directions on the How To Find Your Router's IP Address page.
You should see a box prompting you for your username and password.
- The Default ZTE ZXDSL 831 Router Username is: admin
- The Default ZTE ZXDSL 831 Router Password is: password
Enter your username and password, and then click the Login or OK button to log in to your ZTE ZXDSL 831 router.
ZTE Usernames and Passwords
If your username and password do not work then please visit our Default ZTE Router Passwords page.
Next, try and guess what the password/username was changed to. Use our Find Password App to make this step easier.
If you still can't login to your router because you forgot your ZTE ZXDSL 831 router username and password, use our How to Reset a Router Password guide to set your ZTE ZXDSL 831 router back to its factory settings.
Now we need to find the port forwarding section of your router. Here's how you do it. Starting from the first page in your router:
Start by clicking the Services button at the top of the page.
Next, click the NAT Rule Entry option from the NAT Options drop down menu.
Now, click the Add button at the bottom of the page.

If you are looking for the ports for a different application you can find it by either:
Select RDR from the Rule Flavor dropdown box.
Enter a number that has not yet been used into the Rule ID box.
Leave IF Name set to All.
Select the protocol type of the ports you are forwarding from the Protocol box.
Enter the IP address that you want to forward these ports to into the Local Address From and Local Address To 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.
Leave Global Address From and Global Address To set to 192.168.1.1.
You can leave Destination Port From, Destination Port To and Local Port set to Any Other Port.
If you are only forwarding a single port number then enter that number into both the Local Port, Destination Port From and the Destination Port To boxes. If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Local Port, Destination Port From box and the highest number of that range into the Destination Port To box.
Click the Submit button when you are all done.
Click the Close button at the bottom of the page.
Then, click the IP Filter option at the top of the page.
Now, select Low in the Security Level drop down box.
Then click the Accept option in the Public Default Action, Private Default, and the DMZ Default Action drop down boxes.
Click the Submit button at the bottom of the page.
Click the Admin option at the top of the page.
On this new page, click the Commit & Reboot option.
This takes you to the page you see above. Click the Commit option at the bottom of the page.
Finally, click the Reboot button at the bottom of the page.
