Демилитализованная зона (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.
