DMZ
A DMZ is a host or network segment located “between” internal (local) and external (global)
networks. In the router, the DMZ implements the capability to transfer a request coming to a port of
the router 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 109. The
Firewall / DMZ
page.
To enable the DMZ, select the
Enabled
checkbox, enter the IP address of a host from your network
in the
IP address
field. To choose a device connected to the router's LAN at the moment, select
the relevant value from the drop-down list located to the right of the field (the field will be filled in
automatically) and click the
Change
button.
Note that when the DMZ is enabled, all traffic coming to a port of the WAN interface of the router
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 router's local network, then entering
http://router_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, deselect the
Enabled
checkbox and click the
Change
button.

automatically). Then select the
