4.2.7 DMZ Host
Once a PC on a LAN is set as a DMZ host, it can implement network
communication with Internet without limit.

DMZ Host IP Address: the IP address of a PC to be set as a DMZ
host. DMZ host must be connected to the router’s LAN port.
Note: The router’s firewall cannot have effect on the DMZ host once it
is enabled. Therefore, network security problem may occur. Thus, we
recommend you to enable this function only when necessary and
delete the corresponding settings as soon as you are not using it.
For example, if you want the PC at the IP address of 192.168.1.100
from your router’s LAN side to be shared by Internet users for data and
other resources. For configurations, follow the instructions below:
