Firewall & Dmz - D-Link DIR-300 User Manual

Section 3 - Configuration
This section will allow you to set up a DMZ host and to set up firewall rules.
If you have a client PC that cannot run Internet applications properly from behind the DIR-300, then you can set the client up for
unrestricted Internet access. It allows a computer to be exposed to the Internet. This feature is useful for gaming purposes. Enter

your local network to a variety of security risks, so only use this option as a last resort.
