DSL-2520U
ADSL2/2+ Router with USB and Ethernet Ports
User Manual
Configuring via Web-based Interface
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.
