Model: Deco M9 Plus  
Hardware Version: V9
Firmware Version: 1.9.1 Build 20250612 Rel. 45690

I am trying to set up a Port Forwarding on my Deco router. In the Android App, every time I got to Advanced - NAT Forwarding - Port Forwarding and click Add Port Forwarding Rule, it gives me an address already in use error. However, I don't see any existing port forwarding rule to alter.

Hi, please make sure UPnP is disabled under NAT Forwarding.

After that, please power cycle Deco once to see if it helps.

If the error pops up again, please refer to this link to submit the Deco App log:

How to submit Deco APP log

(Please also add a screenshot of the error message.)

 

Best regards.
