Demilitarized Zone
The Demilitarized Zone window enables you to configure a single computer on the local
side to be exposed to the Internet. All incoming packets will be forwarded to this

Note: Use the demilitarized zone setting only if the virtual server or port range
forwarding options do not provide the level of access required for certain applications.
It is recommended that you contact your ISP for assistance.
