Hello,

Here is the information about Archer C7 1750

Firmware Version: 1.0.5 Build 20171101 rel.37754(5553)
Hardware Version: Archer C7 v4.0

The problem is that the router only open port on Virtual Servers setting. But, the port that configured in UPnP cannot be opened.
I used nmap to check the open port from external IP.

Here is the system log, The UPnp is started but port can only be opened by using Virtual Servers.
