NAT Port, Port Forwarding involves directing a specific port from one network to another. This technique enables external users to access the internal network through the router using that port. Widely used in offices, schools, and homes with multiple computers or Internet-connected devices, it's commonly applied to security cameras. In this article, Mytour will guide you on how to NAT Port and Forward Port with today's popular modems. Follow along, provide feedback, and discuss any issues in the comments below the article.
NAT Port, Forward Port with Common Modems
1. How to NAT Port, Forward port with ZTE F600w Viettel Modem.
Step 1: To NAT Port on the Viettel Modem, first, access the Viettel modem by entering the address 192.168.1.1 in any web browser. Then log in with the default admin credentials: username: admin, password: admin to proceed with NAT Port on the Viettel Modem.
Alternatively, you can also use the credentials admin for both username and the Serial Number printed on the back of the ZTE F600W Modem as the password.
Step 2: Next, go to the Application > Port Forwarding section, then enter the parameters as shown below. Note that the DVR's IP must be a static IP within the LAN. For example, 192.168.1.248 in the example below.
After adding the necessary Ports for NAT, the result will be displayed as shown below, where you can edit or delete as needed.
Step 3: Turn off the firewall by selecting Security >Firewall, then choose Firewall Level and click on the Off option.
Step 4: Then configure DDNS for automatic updating of the dynamic WAN IP (skip this step if the WAN IP is static). Go to Application >DDNS, enable the Enable mode, choose the service provider supported by the modem (e.g., NoIP, Dyndns,...), and press Submit to save.
In the Application >DDNS section, turn on Enable, then select the service provider supported by the modem, for example, Dyndns, and press Submit to save.

Step 1: Use any web browser to access the address 192.168.1.1 and enter the login information User/password as admin.
Step 2: After successful login, proceed to NAT Port for the camera as follows:
Access Application >Port Forwarding, then enter the details: port, camera or DVR IP, enable NAT, and press Add to add to NAT mode. Repeat the process for other cameras and remaining ports.
Step 3: Next, switch to Security >Firewall, uncheck the two lines Remote Telnet Enabled and Remote Https Enabled. This action helps to view smoothly without being blocked by the modem. Normally, when there is a potential threat to the data on the computer, users will block the Port on the modem they are using. How to block the Port correctly, you can follow the article on how to block Port that we have instructed.
Step 4: After NAT, proceed to set up DNS on the modem to update the dynamic IP of the network. If the WAN IP is static, you can skip this step. Enter domain information for the camera, go to Application/ DDNS, choose the connection line to configure, enable the mode, select the DDNS service provider, enter the domain name and the account for that domain. Then press Save to save the domain configuration.
Proceed to enter the domain information for the camera, go to Application/ DDNS, choose the connection line to configure, enable the mode, select the DDNS service provider, enter the domain name and the account for that domain. Then press Save to save the domain configuration.
Step 5: Finally, to complete the process of NAT Port for the GPON FPTelecom modem, restart the modem by going to Maintain >Reboot Device, press Reboot, and wait for about 2-3 minutes for the modem to finish restarting.
3. How to NAT Port, Forward port with Huawei VNPT modem.
Step 1: Firstly, you need to determine the Port to NAT and the IP address of your Camera. (To find Port and IP, go to the Settings of the recorder >Network, and the address will be displayed here).
Step 2: After determining the IP address of the Camera, from your computer, access the default Gateway address of the modem, which is 192.168.1.1. The interface will appear as follows:
