Description
Use this link to configure an IP address that is visible to the
wide area network (WAN). DMZ hosting is commonly referred
to as ―exposed host,‖ and allows you to specify the ―default‖
recipient of WAN traffic that Network Address Translation
(NAT) is unable to translate to a known local PC
A DMZ is used by a company that wants to host its own
Internet services without sacrificing unauthorized access to its
private network. DMZ allows one IP address to be unprotected
while others remain protected. The DMZ is located between
the Internet and an internal network's line of defense that is a
combination of firewalls and bastion hosts
Typically, the DMZ contains devices accessible to Internet
traffic, such as web (HTTP) servers, FTP servers, SMTP (e-mail)
servers, and domain name system (DNS) servers

Network (VPN) protocols and manage Internet Protocol
