3.5.3.2 DMZ Setting
Go to Advanced Setup ->NAT -> DMZ to set DMZ parameters.
A DMZ (de-militarized zone) is a host between a private local network and the
outside public network. It prevents outside users from getting direct access to s server
that has company data. Users of the public network outside the company can access
only the DMZ host.
For example, if you have a local client PC that cannot run an Internet application (e.g.
Games) properly from behind the NAT firewall, then you can open the client up to
unrestricted two-way Internet access by defining a DMZ Host.
