3.6.5 DMZ

configuring the Special Applications function, then you can open the client up to unrestricted two-way 

Internet access. 

Enter the IP address of a DMZ host to this screen. Adding a client to the DMZ (Demilitarized Zone) may 

expose your local network to a variety of security risks, so use this option only as the last resort. 

 

 

Enable: 

Enable/disable DMZ. (Default: Disable) 

Public IP Address:

 The IP address of the WAN port or any other Public IP addresses given to you by your 

ISP.

 

IP Address of Virtual DMZ Host: 

Enter the DMZ host IP address.
