Dmz - TP-Link TL-ER5120 User Manual

3.1.5 DMZ

DMZ (Demilitarized Zone) is a network which has fewer default firewall restrictions than the LAN does.
TL-ER5120 provides a DMZ port to allow all the local hosts connected to this port to be exposed to the
Internet for some special-purpose services, such as such as Internet gaming and video-conferencing.
The DMZ physical port can work in Public mode and Private mode.
In Public mode, the DMZ port allows the Hosts in DMZ to directly communicate with Internet via routing
mode using public IP address. However, the Hosts in DMZ cannot access LAN.
Figure 3-17 DMZ – Public Mode
In Private mode, the DMZ port allows the Hosts in DMZ to access Internet via NAT mode which
translates private IP addresses within DMZ to public IP addresses for transport over Internet. The
Hosts in DMZ can directly communicate with LAN using the private IP addresses within the different
subnet of LAN.
