Am I doing the right port forwarding in the ADSL router?

Question

network hardware

ADSL Router TD854W. The order is: 1) user server - RDR (from the name of the game), 2) - protocol - UDP, 3) - Wan - interface, 4) - Wan interface - pppoe1 -, 5) Wan port - 6672, - 6) open LAN port - 6672, 7) - LAN IP address - I enter the local IP address of the computer, this is the ip4 address. And as a result, the 2ip site shows port 6672 is closed. What am I doing wrong? There is a white IP, I connected it.

Answer 1

UDP ports are not so easy to check for openness. Sites usually do this over TCP.
The easiest way to check is by simply trying to connect from somewhere to you at an external address directly from the game.
Well, try turning off the firewall in the OS. Or customize.
