DMZ
A DMZ is a host or network segment located “between” internal (local) and external (global)
networks. In the gateway, the DMZ implements the capability to transfer a request coming to a port
of the gateway from the external network to a specified host of the internal network.
On the
Firewall / DMZ
page, you can specify the IP address of the DMZ host.
Figure 140. The
Firewall / DMZ
page.
To enable the DMZ, move the
Enable
switch to the right.
Enter the IP address of a host from your network in the
IP address
field. To choose a device
connected to the gateway's LAN at the moment, select the relevant value from the drop-down list
(the field will be filled in automatically).
Click the
APPLY
button.
Note that when the DMZ is enabled, all traffic coming to a port of the WAN interface of the
gateway is directed to the same port of the specified IP address. Also note that virtual servers have
higher priority than the DMZ host. In other words, if there has been created a virtual server that
directs traffic from external port 80 to a port of the device from the gateway's local network, then
entering
http://gateway_WAN_IP
in the address bar, users of the external network are
directed to the specified port and IP address configured for the virtual server, but not to port 80 of
the device with the IP address specified on the
Firewall / DMZ
page.
To disable the DMZ, move the
Enable
switch to the left and click the
APPLY
button.
