Dmz And Firewall Setup - D-Link DSL-2640R User Manual

Advanced Configuration
Use the Firewall and DMZ menu to enable or disable basic firewall protection from Denial of Service and other attacks from the WAN.
Firewall Settings
Enable the Firewall to block Denial of Service attacks, flood pings, port scans and other
common exploitative attacks that might come from the Internet. This is enabled by
default. To disable it, click the Enable Firewall box to remove the check mark and click
the Apply Settings button.
DMZ Settings
Firewalls may conflict with certain interactive applications such as video conferencing or
playing Internet video games. For these applications, a firewall bypass can be set up
using a DMZ IP address. The DMZ IP address is a "visible" address and does not benefit
from the full protection of the firewall function. Therefore it is advisable that other security
precautions be enabled to protect the other computers and devices on the LAN. It may
be wise to use isolate the device with the DMZ IP address from the rest of the LAN.
For example, if you want to use video conferencing and still use a firewall, you can place
the server in the DMZ. The IP address of this server will then be the DMZ IP address.
You can designate the server's IP address as the DMZ by typing in the IP address in the
DMZ IP Address space provided and then enabling its status by selecting the Enable
DMZ option. Click the Apply Settings button at the top of the window when you are
finished.
