Path: Advanced > DMZ
If you have a local client computer that cannot run an Internet application properly behind the firewall,
you can configure the computer for unrestricted two-way Internet access by defining it as a Virtual DMZ
host. A DMZ allows a single computer on your LAN to expose its ports to the Internet. When doing this,
the exposed computer is no longer “behind” the firewall. Therefore, placing a computer in the DMZ
should be considered temporary because the firewall is no longer able to provide any security to it.
