Hi,
Below is the instruction to setup port forwarding on the Deco M4.
https://www.tp-link.com/support/faq/1797/
What is the device you need open port for? Meanwhile, please ensure that the IP address and mac address matches the device.
In the same network, please test whether you can access it with the device's IP address and port number; meanwhile, you can use the WAN IP plus port number to test.
Besides, please use telnet to test:
1. in the same network, please go to run—cmd—telnet lan ip port number
2. in external network, please run—cmd—telnet wan ip port number
Note: Please show us the pictures of the test results.
Good day.

Hello,
May I know what is the WAN/Internet IP address of the Deco M4?
Please use the computer in the same network to do the tests below and tell us the results.
A. Use LAN IP+port to test if the server can be accessed from LAN;
B. Use WAN IP+port on LAN PC to test if the port is opened.
Meanwhile, please disable the firewall and anti-virus software on the computer.
Any updates, just let us know.
