Personal Firewall and VNC:

I am attempting to get VNC to work with my Sunbelt Personal Firewall. I am using RealVNC. There is a test button with this program that confirms if the configuration is ready. When I disable the firewall, the test works, however, when I enable the firewall, the test fails. The RealVNC instructions for use with the Windows firewall are:

"Use Windows Firewall (Windows XP Service-Pack 2 and newer). Recent versions of Windows XP include a built-in firewall. From Service Pack 2 onwards, the firewall can be easily configured to allow particular applications to open whichever ports (TCP ports 5800 and 5900 for VNC) they require. By adding an ‘Application Exception’ to the Windows Firewall for the VNC Server, both User- and Service- mode servers can be made accessible remotely without the need for port numbers to be specified explicitly. The VNC server is able to detect Windows Firewall and configure it automatically when the VNC Server Properties dialog is dismissed."

Please assist.

Thank you

    Thank you for contacting Sunbelt Software.

    To get Sunbelt Personal Firewall to let applications on to the Internet, we'll have to temporarily switch Sunbelt Personal Firewall to advanced mode so it can create a rule for your applications.

    Please open Sunbelt Personal Firewall. You can do that by double-clicking the purple shield icon, which is in the bottom-right of your screen, near the system clock.

    Then, click the Network Security tab, found on the left. Now on the right you'll see a list of applications. Find the one called "Any other application."

    Click each of the 4 columns until the columns read ASK ASK ASK ASK. Then click the Apply Button.

    Now, try running all your Internet programs now. Notice Sunbelt Personal Firewall will pop up with a dialog box that asks you to click "PERMIT" or "DENY" to an application. Be sure to CHECK the check box above these choices so you can make a rule for this application, and then click the "PERMIT" button. Do this for each time you receive the message. Use your programs as normal for a few minutes until you are sure you've got every program setup.

    Sunbelt Personal Firewall has now made a rules for these programs. Go back to Sunbelt Personal Firewall where we were and change "Any Other Application" back so they read in this order: DENY PERMIT DENY PERMIT by clicking each of the 4 columns until they are changed to those values, then click Apply.

    Let us know if you continue to have problems.
