Answer | The DMZ Host feature allows the option to run a publicly accessible server within the home network. This enables the SBG7600AC2 to forward all traffic to the designated DMZ Host device such as Web Server, Mail Server, Digital Video Recorder (DVR) or gaming device.  That designated DMZ Host device will operate outside of the SBG7600AC2 firewall and allow remote access from the Internet to the home network.  This document describes how to gather the client IP address and setup DMZ Host in the SBG7600AC2.
CAUTION: The designated DMZ Host device is not protected by the SBG7600AC2 firewall.  It is exposed to the Internet and thus vulnerable to attacks or hacking from any computer on the Internet.  Consider carefully before configuring a device to be in the DMZ.  It is recommended to enable software firewall on that device or use a more secure method of forwarding traffic such as Port Forwarding.  Please refer to Answer # 18415 - SBG7600AC2: Port Forwarding Setup. Â
The following are examples of scenarios in which DMZ Host is useful:
- When the port number or protocol in an in-bound application cannot be anticipated. Â For example, some network games select arbitrary port numbers when a connection is opened.
- When all unsolicited traffic needs to be forwarded to a specific device in the network.
- When an application does not work well with port triggering or port forwarding.
After completing the DMZ Host setup, it is recommended to reserve the IP address for the client device setup for DMZ.  Please refer to Article # 18395 - SBG7600AC2: IP Address Reserve Setup.
Requirement
The client device IP Address is required to setup DMZ Host. Â It can be found in the SBG7600AC2 Web Manager or from the client device's network information.

 - On the Login page, enter admin in the User Name field.
 - Enter password or a customized password in the Password field.
NOTE: When using the default password to login, it may be required to set a unique password to proceed to the Web Manager. For assistance with Web Manager Access, refer to article # 18386 – SBG7600AC2: Web Manager Access.
 - Click the Apply button.  The System Basic Setup window will appear.
 - On the System Basic Setup page, click the LAN Setup link on the top menu.  The LAN Settings page will appear.

 - On the Client List page, copy the client's IP Address under Attached Client List section to use for the DMZ setup.
NOTE: If the client is not found it may not be powered on or not connected to the network. Â When the IP Address is statically assigned to the client, the device will appear under the Reserved IP Client List.
 - Click the Firewall link on the top menu.  The Firewall Settings page will appear.
 - On the Firewall Settings page, click the DMZ link on the left-hand menu.  The DMZ Settings page will appear.
