Firewall & DMZ
The router already provides a simple rewall 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 Demilitarised Zone. DMZ allows computers behind the router rewall to be accessible to Internet trac. Typically, your DMZ would
contain Web servers, FTP servers, and others.
