Hi,

It's a been a year that I'm using a Deco X60, perfectly working, great product until recently, any Port Forwarding rules that I add doesn't work. 

Hard to tell if that had started since the latest firmware in January or if it's due to a iOS App update. 

I've checked several posts and forums on the internet. Some recommend to review the IPV4 Wan connection in case of a GNAT with the ISP. That's not the case for me (using TPG/Australia).
 

I've checked the port on the local machine. All good. 
I've used several website and scanner to check if open and all have failed. 
I've start/stop one or all mesh point. Nothing helped. 
 

The weird thing is that some rules set up prior ~Dev 2020 worked but any new rule since will not work at all, regardless of the port number, port range or even the client selected. 
 

Hard to debug or diagnose without a more granular Admin interface (I get it's a consumer product - but the App is pretty limited and the Web Admin is basically inexistant - a topic that TP-Link could work on - another topic/subject)
 

Any idea or thoughts on what to do next?
