DMZ
NAT and the firewall features of your DFL-600 may conflict with certain
interactive applications such as video conferencing or playing Internet video
games. For these applications, a bypass can be set up using the DMZ port and
a corresponding DMZ IP address. The DMZ IP address is “visible” to the
Internet (or WAN) and does not benefit from the full protection of the NAT
function. Therefore it is advisable that other security precautions be enabled
to protect the DMZ device and other computers and devices on the LAN that
may be exposed. It may be wise to run some sort of firewall software on
these computers and devices.
For example, if you want to use video conferencing and still use NAT, you
can use the DMZ port and DMZ IP address. In this case, you must have a PC
or server through which video conferencing will take place, and that
computer is assigned the DMZ IP address.
By default, the DMZ IP address is 192.168.1.1 with a subnet mask of
255.255.255.0. Note that the DMZ IP address is on a different subnet (the
192.168.1.x subnet) than the LAN ports (by default, the LAN ports are
assigned to the 192.168.0.x subnet).
