DMZ Host
You can use the DMZ Host screen to set up a default DMZ computer. Specifying a default
DMZ computer allows you to set up a computer that is available to anyone on the Internet for
services that you have not defined. To minimize security risks, set up the DMZ host only if
you are willing to risk open access. If you do not define a DMZ host, the gateway discards
any undefined service requests.
