System Broadband Link Home Network Firewall
Edit Firewall Settings

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 profile. (To create a user-defined profile, you will need to know protocol and port information.)

To Allow Users Through the Firewall to Hosted Applications...
1Select a computer
Choose the computer that will host applications through the firewall:

2Edit firewall settings for this 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.
Hosted Applications:

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: Once DMZplus mode is selected and you click DONE, 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.
