DMZ

Firewalls may conflict with certain interactive applications such as video conferencing or playing Internet video
games. For these applications, a firewall bypass can be set up using a DMZ IP address. The DMZ IP address is a
"visible" address and does not benefit from the full protection of the firewall function. Therefore it is advisable
that other security precautions be enabled to protect the other computers and devices on the LAN. It may be
wise to use isolate the device with the DMZ IP address from the rest of the LAN.
For example, if you want to use video conferencing and still use a firewall, you can use the DMZ IP address
function. In this case, you must have a PC or server through which video conferencing will take place. The IP
address of this PC or server will then be the DMZ IP address. You can designate the server's IP address as the
DMZ by typing in the IP address in the IP Address space provided and then enabling its status by clicking the
Enabled radio button and then click Apply.
For the system that uses the DMZ IP address, you may want to manually assign an IP address to it and adjust
your DHCP server addresses so that the DMZ IP address is not included in the DHCP server range. This way you
avoid possible IP address problems if you reboot the DMZ system.
DMZ menu
To designate a DMZ IP address, select the Enabled radio button, type in the IP Address of the server or
device on your LAN, and click the Apply button. To remove DMZ status from the designated IP address, select
the Disabled radio button and click Apply. It will be necessary to save the settings and reboot the Router before
the DMZ is activated.
