Fastest ZyXEL C3000Z Router Open Port Guide

A ZyXEL C3000Z router contains a basic firewall to help protect your home network. A Firewall blocks incoming connections by nature. Sometimes you need to unblock some of these connections so you can run a game or application. This is called opening a port or port forwarding. Port forwarding is literally forwarding a port from the Internet to your home network.

Follow the steps below to open ports in your ZyXEL C3000Z router:

  1. Set up a static IP address on the computer or device that you are forwarding ports to.
  2. Login to your ZyXEL C3000Z router.
  3. Find the Port Forwarding section in your ZyXEL C3000Z router.
    • Click on the Advanced Setup button at the center of the screen.
    • Find the Port Forwarding link located near the left of the screen and click on it.
  4. Create a Port Forwarding entry.

If this sounds difficult you are not alone. We will walk you through each step in opening a port for the ZyXEL C3000Z router.

Step 1

In order to keep the ports in your router open, even after a reboot or disconnect, it is important to set up a static IP address in the device that you are forwarding a port to.

  • Recommended - Our free program will setup a static IP address for you.

  • Or follow our Static IP Address guides to setup a static IP address.

After setting up a static ip address on your devices you need to login to your router.

Step 2

The ZyXEL C3000Z router uses a web interface to display router settings. In order to login to the ZyXEL C3000Z router you need to use a web browser.

Open your favorite web browser. If you don't have a favorite or are not sure what this means, open up Chrome, Firefox, or Internet Explorer. If you are already in a browser window, go ahead and open up a new tab.

We have simplified this step for you with this link: Login to your C3000Z Router

Find the address bar in your browser window. This is usually found at the top of the page, like in the image below.


192.168.0.1

Look at the screenshot above and find 192.168.0.1 in the address bar. This is your router's IP address (which is sometimes called the computer's default gateway.)

The ZyXEL C3000Z router's default IP address is: 192.168.0.1

After typing your router's IP address into the address bar, make sure to click the enter button on your keyboard. You should see a box similar to the one shown below.

login

Enter the username and password for your ZyXEL C3000Z router. Note: If you have changed these numbers in the past, you will need to enter in the those values.

  • The default ZyXEL C3000Z Router Username is: admin
  • The default ZyXEL C3000Z Router Password is: printed on router

Once you have entered your username and password, remember to click the Apply button to login to your ZyXEL C3000Z router.

ZyXEL Usernames and Passwords

If the username or password did not work check out our Default ZyXEL Router Passwords page.

If you are unable to log in even after trying the above list of passwords you may need to consider a reset for your router. Our guide How to Reset a Router can help you with that. After resetting the ZyXEL C3000Z router your username and password will be reverted back to factory defaults.

Step 3

After successfully logging in to your ZyXEL C3000Z router you should see the router's home page on your screen. Find the Port Forwarding section of your router.

  • Click on the Advanced Setup button, which can be found at the center of the screen.
  • Find the Port Forwarding link at the left of the screen and click on it.

You should now be on a page called Port Forwarding.

Step 4

Forwarding ports in your router creates a path that allows data to get through your network firewall and it is possible that this could lead to malicious traffic on your network. So make sure that it is really necessary for you to forward a port before actually doing so. However, the risk is very low, so do not let this warning stop you from making this change if you need to.

Here are the ports to forward for Xbox Live:

TCP Ports:3074
UDP Ports:3074

If you are looking for the ports for a different application you can find it by either:

  1. Select Manually Enter IP Address from the Select Device drop down box.

  2. Go ahead and enter the IP address that you are forwarding ports to into the Enter IP Address box. It is possible for this to be either the IP address of your computer or of any other device on your network that you want ports forwarded to.

  3. To forward a single port, enter the port number into the Starting Port and the Ending Port boxes. To forward a range of ports, enter the lowest number in the range into the Starting Port box. Then enter the highest number in the range into the Ending Port box.

  4. Select the protocol type of the ports that you are forwarding from the Protocol dropdown box. If your router has the option of Both, then go ahead and select that. Otherwise select either TCP or UDP as needed. If you need to forward a port for both TCP and UDP but your router does not have Both, then you will need to create two entries.

  5. Click on the radio button that says All IP Addresses.

  6. To apply these changes, remember to click the Apply button at the bottom of the page when you are completely finished.

Test Your Open Ports

Finally, test your network to see if you have forwarded ports in the ZyXEL C3000Z router correctly. To do this you can use Network Utilities, which includes a free Open Port Checker tool. Open Port Checker is the only online port-checking tool that has Guaranteed Results.
