8.3 DMZ
Go to Forwarding DMZ, in order to visualize and configure the DMZ host, as shown in
the screen below (Figure 8-6). The DMZ host feature allows one local host to be exposed to
the Internet so as to gain access to certain applications, such as Internet gaming or video-
conferencing. DMZ host forwards all the ports at the same time. Any PC whose port is being
forwarded must have its DHCP client function disabled, and should also have a new static IP
Address assigned to it, because its IP Address may be changed when using the DHCP
function.
To assign a computer or server to be a DMZ server:
1. Click the Enable radio button
Enter the local host IP Address in the DMZ Host IP Address field.
2.
3. Click the Save button.
Note: Once you set the DMZ host, the firewall protection for that host will be disabled.
