Hi,

You opened port 16000 via virtual server, while according to your description, the kane wrath with port range 8088-65505, so it is suggested to use DMZ.

Meanwhile, the current IP address seems a private IP address, which is 10.x.x.x, that is why you failed to open ports; To make it work, you need open port on the front-end device or ISP's end which has the public IP address for the TP-Link router. 

May it help and have a nice day.
