Chapter 5 Network Tab
The hosts using private IP addresses visit Internet through NAT (Network Address Translation)
technology. NAT can transfer private IP addresses into public IP addresses to realize the
communication from internal hosts to external hosts.
If the hosts on the Internet want to visit the hosts on local area network, the forwarding function
should be used, including DMZ, Virtual server, Port triggering and UPnP.
DMZ Check the Enable box to use the DMZ function. DMZ (Demilitarized Zone)
specifically allows one computer/device behind NAT to become
“demilitarized”, so all packets from the external network are forwarded to
this computer/device. The demilitarized host is exposed to the wide area
network, which can realize the unlimited bidirectional communication
between internal hosts and external hosts.
DMZ IP Specify the IP address of the local host network device. The DMZ host
device will be completely exposed to the external network. Any PC that was
used for a DMZ must have a static or reserved IP Address because its IP
Address may change when using the DHCP function.
