Why port forwarding feature is not working on my router?
Please follow the steps below for troubleshooting port forwarding failures on a TP-Link router.
Step 1: Make sure the server is accessible from the internal network
You will want to double-check the IP address and the port number of the server. Check if you can access that server in the local network. If you are unable to access the server in your local network, please check the settings of your server.
Step 2: Check the port forwarding settings in the router.

Step 3: Pay attention to the WAN IP address in the status page
If there are still problems, please check the WAN IP of the router. Verify the router is getting a public IP address. If it is a private IP address, which means it's not enough to only open port on the TP-Link, you have to do the same setting on the modem router as well.
But for the CG-NAT ISP: Comporium and Direct link - radio service, provide the customer a private IP, that will cause you can’t use the OpenVPN or port forwarding and affect the NAT Type. You can contact the ISP and ask them to offer a Statis IP address.
What's the WAN IP address? Here is the instruction.

For 4G LTE Router:
WAN IP should be a public IP address. The WAN IP is assigned dynamically by ISP. If the WAN IP address of the router is not a public IP address, but a private IP address, that means there is another NAT device connected to the WAN port of the router. You need to open the service ports on that device as well.
For most of the 4G LTE router, the internet service provider usually gives the private IP Address. So, if you want to do the port forwarding, please contact your internet service provider to assign you a public IP address or do the port forwarding in their part.
Please google if you don't know how to tell Public IP Address or Private IP Address.
Feel free to contact us if it's not working after the above steps.
