4-10 DMZ Host
The DMZ Host application allows unrestricted 2-way communication between a single LAN
computer and other Internet users or servers. This application is useful for supporting special-
purpose services such as video-conferencing and gaming, which require proprietary client
software and/or unrestricted 2-way user communication. To use this application, you should
have a fixed Public IP Address from your ISP.
Note: In order to provide unrestricted access, the Firewall provided by the NetComm
Cable/DSL Firewall Router to protect this port is disabled, thus creating a
potentially serious security risk. It is recommended that this application
should be disabled when it is not in use by entering “0” in the “DMZ Host”
field.
1. Before setting up a LAN computer to act as a DMZ Host, configure it with a fixed IP
Address.
2. In the “One Page Setup” screen, ensure the Private IP Address is set to the NetComm
Cable/DSL Firewall Router’s default setting of 192.168.1.1. In the Public IP Address area,
select “Specify an IP Address”, then enter the IP Address and other necessary information
provided by your ISP.
3. Click “DMZ Host” from the Advanced Menu. Enter the fixed IP Address of the Exposed
Host computer in the “DMZ Host” IP Address location. Remember, entering “0” will
disable this application.
4. Click “Apply”.
4-11 Log
The Log application allows the administrator to trace Internet access. You can send the record to
specific LAN computers for remote monitoring, but can also watch the incoming (WAN to
LAN) and outgoing (LAN to WAN) traffic in the “Log Settings” page.
