6.15 DMZ Screen
DMZ allows other devices over the Internet to access a DMZ host device within your local network. DMZ,
which stands for "DeMilitarized Zone", is a network between the WAN and the LAN that is open to the
WAN but still has firewall protection. Devices on the WAN can initiate connections to devices on the
DMZ but not to those on the LAN. You could put servers such as mail servers, HTTP/HTTPS web servers and
FTP servers on the DMZ to provide services to hosts on the WAN as well as hosts on the LAN. You first need
to assign a DMZ host to use DMZ.
Use the following screen to specify the IP address of a default server to receive packets from ports. To
access this screen, click Router > Firewall > DMZ.

6.16 DDNS Settings Screen
Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS
services so that anyone can contact you (in applications such as NetMeeting and CU-SeeMe). You can
also access your FTP server or Web site on your own computer using a domain name (for instance
myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP
address that changes each time you reconnect. Your friends or relatives will always be able to call you
