On the ZyWALL VPN & Internet Security Gateways [2 plus, 5/35/70] the DeMilitarized Zone [DMZ] auto-negotiating 10/100 Ethernet port(s) utilizing Secure Zones Technology provides a way for public servers [Web, e-mail, FTP, etc.] to be visible to the outside world (while still being protected from DoS [Denial of Service] attacks such as SYN flooding and Ping of Death). These public servers can also be accessed from the secure LAN. The DMZ zone has its own DHCP service and all zones are securely separated by firewall rules.

The Ethernet ports in the ZyWALL 5/35/70 switch supports three separate broadcast zones: (1) LAN, (2) DMZ and (3) WLAN; connections between these three broadcast zones always go through the firewall [consequently they require firewall rules]

By default the firewall allows traffic between the WAN and the DMZ, traffic from the DMZ to the LAN is denied, and traffic from the LAN to the DMZ is allowed. Internet users can have access to host servers on the DMZ but no access to the LAN, unless special filter rules allowing access were configured by the administrator or the user is an authorized remote user.

All your public servers should be connected to the DMZ port. If you have more than one public server, connect a switch to the DMZ port.

Keep all sensitive information off the public servers connected to the DMZ port. Store sensitive information on LAN computers.

Note: In the world of Computer Networks most consumer grade mass produced Network Routers refer to a "DMZ host" —This is NOT a true DMZ by definition. Many consumer grade routers [Linksys | Belkin | Netgear] refer to a DMZ host. These are pseudo or naked DMZ's, as they provide no security between that host and the internal network like that provided by ZyWALL as described above. Most consumer grade home router's DMZ host is a host on the internal network that has all ports exposed, except those ports forwarded otherwise.
