4-9 DMZ Host
The DMZ Host application allows unrestricted 2-way communication between a single
LAN PC and other Internet users or servers. This application is useful for supporting
special-purpose services such as video-conferencing and gaming, that require proprietary
client software and/or 2-way user communication.
To use this application, you must first obtain a fixed Public IP Address from your ISP.
Note that in order to provide unrestricted access, the Firewall provided by the Wireless
Security Router to protect this port is disabled, thus creating a potentially serious security
risk.
It is recommended that this application is disabled when it is not in use by entering “0” in
the “DMZ Host”field.
The Multi DMZ allows you to map the public IP addresses to your LAN PCs, should you
get more than one public IP address from your ISP. This function is useful to set up your
servers, such as an FTP server, web server, and so on, with public IP addresses, but still
keep them within your LAN group.
With the public IP addresses, Internet users will access your servers more easily and
those servers can still communicate with other PCs in you LAN by using Network
Neighborhood.
