Hello Good day,

I created a Port Forwarding on the router  following this step guide https://www.tp-link.com/en/support/faq/2132/. 

When I checked my configurations on port checker it is Open(working).

But when I accessing the Public IP together with port number in a different location it was unable to access the machine.

Here is the details for my current setup.

Public IP: 120.28.109.110

Port Number: Internal Port 3389, External Port 3391

IP Address of the machine remote: 10.30.0.8

Note: Internet is working fine on both locations

I've tried to access different address on web browser:

http://120.28.109.110:3391 -- None-reponse

https://120.28.109.110:3391 -- This site can't be reached

Alsto tried 20.28.109.110:3391

Thank you
