DMZ
A DeMilitarized Zone (DMZ) is a network off one of the LAN ports that acts as a kind of buffer between
the external (public Internet) network and your secure network on the other LAN interface. The DMZ
gives access to services required from both the external network and the secure network. The services
are typically HTTP/FTP (Web) servers for public access, an HTTP/FTP proxy server, an SMTP server
and a News (proxy) server. Mail servers and News servers for internal use are placed on the secure
network. Through the use of access control list and Firewall, you prohibit access from the Internet to
your secure network while still providing access to services on the DMZ.
