Firewall application, pinholes and DMZ

Allow device application traffic to pass through firewall

By default, the firewall blocks all unwanted access from the Internet. You can allow access from the Internet to applications running on computers inside your secure home network by enabling firewall pinholes. Opening firewall pinholes is also known as opening firewall ports or firewall port forwarding. To do this, associate the desired application with the computer below. If you cannot find a listing for your application, you can create a user-defined application with the protocol and port information.

To allow Internet traffic or users through the Firewall to your LAN devices, applications and servers

Note: Use IP address format - xxx.xxx.xxx.xxx, where xxx represents the number (0-255).

2) Edit firewall settings for this computer

Note: Only one selection (e.g., Maximum Protection, Individual applications or DMZPlus) can be applied to a selected computer at a time. Changing the option below will remove any prior selection for that computer.

Maximum protection - Disallow unsolicited inbound traffic

Allow individual application(s) - Choose the application(s) that will be enabled to pass through the firewall to this computer. Click ADD to add it to the Hosted Applications list.

Add a new user-defined application

Allow all applications (DMZplus mode) - Set the selected computer in DMZplus mode. All inbound traffic, except traffic which has been specifically assigned to another computer using the "Allow individual applications" feature, will automatically be directed to this computer. The DMZplus-enabled computer is less secure because all unassigned firewall ports are opened for that computer.

Note: On LAN devices which have a Private IP address, once DMZplus mode is selected and you click save, the system will issue a new IP address to the selected computer. The computer must be set to DHCP mode to receive the new IP address from the system, and you must reboot the computer. If you are changing DMZplus mode from one computer to another computer, you must reboot both computers.
