1. DMZ Host Configuration
You can set up your personal computer or network-ready device to be a public
or local DMZ hosts. In general, Internet applications use only one unique port
and can pass through a Broadband Router by enabling Virtual Server. However,
some special applications need to implement multiple ports, port ranges,
dynamically assigned ports, and special protocols. Broadband Router can
support the transparent pass-through of these special applications, such as FTP,
NetMeeting/H.323, MSN Messenger, etc. Enable Local DMZ Host when you
have problems running these applications. Besides, you can activate Public
DMZ Host to set up a server and retrieve the traffic initiated from the Internet.
A.
Local DMZ Host
To run the special applications, you can assign a device with a LAN IP address
as Local DMZ Host. Then any service request of application initiated from
the Internet will be forwarded to the dedicated LAN host with the LAN IP
address.
