FIREWALL & DMZ
The router already provides a simple firewall by virtue of the way NAT works. By default NAT does not respond to unsolicited incoming requests on
any port, thereby making your WAN invisible to Internet cyber attackers.
DMZ means 'De Militarized Zone'. DMZ allows computers behind the router firewall to be accessible to Internet traffic. Typically, your DMZ would
contain Web servers, FTP servers, and others.
