by DMZ
When a PC is set to be a DMZ (Demilitarized Zone) host on the local network, it is totally
exposed to the internet, which can realize the unlimited bidirectional communication
between internal hosts and external hosts. The DMZ host becomes a virtual server with
all ports opened. When you are not clear about which ports to open in some special
applications, such as IP camera and database software, you can set the PC to be a DMZ
host.
Note:
When DMZ is enabled, the DMZ host is totally exposed to the internet, which may bring some potential safety hazards. If
DMZ is not in use, please disable it in time.

as a DMZ host with all ports open.
