client device (e.g., computer or laptop) on the Internet. Consider carefully before
configuring a device to be in the DMZ.
You can configure one client device on your home network to be the DMZ Host. That client
device will operate outside of the SBG8300 firewall and allow remote access from the
Internet to your client device, gaming device, or other IP-enabled device. The DMZ Host
feature will only allow outside users to have direct access to the designated DMZ Host
device and not your home network.
To create the DMZ host:
