Configuring DMZ

A Demilitarized Zone is used to provide Internet services without sacrificing unauthorized access to its local private network.

Typically, the DMZ host contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-

mail) servers and DNS servers. All inbound packets will be redirected to the computer you set. It also is useful if you run some

applications (e.g. Internet games) that use uncertain incoming ports.

Enable DMZ

Enables the DMZ.

DMZ Host IP Address

Input the IP Address of the computer that you want to expose to the
Internet.
