11.1 DMZ Host/ Port Range Forwarding
11.1.1 DMZ Host
When the NAT mode is activated, sometimes users may need to use applications that do not
support virtual IP addresses such as network games. We recommend that users map the device actual
WAN IP addresses directly to the Intranet virtual IP addresses, as follows:
If the "DMZ Host" function is selected, to cancel this function, users must input "0" in the following
"DMZ Private IP". This function will then be closed.
After the changes are completed, click "Apply" to save the network configuration modification, or
click "Cancel" to leave without making any changes.
11.1.2 Port Range Forwarding

use the firewall function to set up the host as a virtual host, and then convert the actual IP addresses
