6.2 DMZ
A DMZ allows a single computer on your LAN to expose ALL of its ports to the Internet.
By doing this, the exposed computer is no longer ‘behind’ the NAT/firewall. DMZ is far
easier to set up than port forwarding in terms of setting up a virtual server, but it exposes
your entire computer to the Internet.
Note:
Sometimes TCP/IP applications require very specialized IP
configurations that are difficult to set up. In this case, placing your
computer in the DMZ is the only way to get the application working.
Following is an example of DMZ, which redirects all of low ports on WAN
interface to a host with internal IP address 192.168.30.143.
Click the DMZ menu item in the menu bar on the left to display the current DMZ
configuration setting.
You can decide to Enable or Disable DMZ. Enter the internal IP address if DMZ is enabled.
Then click the
Apply
button to submit the setting.
