SVG2482AC: DMZ Setup

How do I setup a DMZ Host in my SVG2482AC Gateway?
The DMZ Host feature allows the option to run a publicly accessible server within the home network.  This enables the SVG2482AC 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 SVG2482AC firewall and allow remote access from the Internet and not the home network.  This document describes how to gather the client IP address and setup DMZ Host in the SVG2482AC.

CAUTION: The designated DMZ Host device is not protected by the SVG2482AC 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 # 16856 - SVG2482AC: Port Forwarding Setup.  

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.  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 port forwarding.  Please refer to Article # 16858 SVG2482AC: IP Address Reserve Setup.

The client device IP Address is require to setup DMZ Host.  It can be found in the SVG2482AC Web Manager or from the client device's network information.
