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 DSL 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.
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 (the
field will be filled in automatically).
If you want users of the router's LAN to access the host using the router's external IP address, select
the Enable NAT Loopback checkbox. If a DDNS service is configured on the Advanced /
DDNS page, also the users can access the host via the router's domain name.
Click the Apply 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 Apply button.
