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 Status 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. To configure the Router’s DMZ IP address, click the Advanced tab at the top of the
screen and then the DMZ tab to the left.
