Allow All Applications (DMZplus)

DMZplus is a special firewall mode that is used for hosting applications if you are still not able to get an application to operate properly using the “Allow individual application(s)” option.

DMZplus

When in DMZplus mode, the designated computer:
  • “Shares” your Router Address (system’s IP address).
  • Appears as if it is directly connected to the Internet.
  • Has all of the unassigned TCP and UDP ports opened and pointed to it.
  • Can receive unsolicited network traffic from the Internet.
NOTE: Although the DMZplus computer appears to Internet users as though it is directly connected to the Internet, it is still protected by your system firewall. All traffic is inspected by the firewall's Stateful Packet Inspection engine and all known hacker attacks continue to be blocked.

Since all filtered traffic is forwarded to the designated computer, DMZplus mode should be used with caution. In most situations, you can use the “Allow individual application(s)” option to support access from the Internet to applications on your network.

NOTE: DMZplus can only be configured for one computer on your local network at a time.

The Firewall Settings page allows you to enable DMZplus and select which computer will run in DMZplus mode.

Configuring DMZplus
To configure a computer on your network for DMZplus mode:
System Setup
  1. Select the computer to which you would like to have all data sent.
  2. Select “Allow all applications (DMZplus mode).”
  3. Click DONE.
  4. Access the selected computer and complete Computer Setup.
Computer Setup
  1. Confirm that the computer is configured for DHCP. If it is not, configure it for DHCP.
  2. Restart the computer.
When the computer restarts, it receives a special IP address from the system and all unassigned TCP and UDP ports are forwarded to it.
WARNING: A computer in DMZplus mode is less secure because all available ports are open and all incoming Internet traffic is directed to this computer.

Disabling DMZplus
To disable DMZplus mode:
System
  1. Select the computer for which you would like to disable DMZplus.
  2. Select “Maximum protection.”
  3. Click DONE.
  4. Access the computer that is in DMZplus mode and complete Computer Setup.
Computer Setup
  1. If the computer will continue to automatically obtain an IP address, proceed to step 2. If the computer will have a static IP address, configure it with a valid static IP address.
  2. Restart the computer.
