Section 7: Multi DMZ & UPnP

Multi DMZ
The Multi DMZ feature allows each WAN port IP address to be associated with one (1) computer on your LAN. All outgoing traffic from that PC will be associated with that WAN port IP address. Any traffic sent to that IP address will be forwarded to the specified PC. This allows unrestricted 2-way communication between the “DMZ PC” and other Internet users or servers.

Note: The “DMZ PC” is effectively outside the Firewall making it more vulnerable to outside attacks. Enable the DMZ feature when required.

Multi DMZ - Settings

Private IP Address (LAN)

Access Group
You can decide which users to have the authority of using DMZ by defining the groups.

Direction
For DMZ you can set the traffic direction to inbound, outbound, or both (bi-directional).

Universal Plug & Play (UPnP)

The UPnP function can easily setup and configure an entire network, enable discovery, and control network devices and services.

When UPnP is enabled, an icon will show up on network neighborhood (Microsoft Windows OS) using the model name of your Twin WAN Gateway (XC-DPG502, XC-DPG503, etc.). Every time you add a new network device with port mapping, the new network device will appear on the mapping list.
