What is a firewall?

A firewall is a device that protects a computer or network from unauthorised, unwanted, malicious or covert attempts to establish channels of communication with other computers or devices.

 

Configuring your firewall to allow Designer to operate

If you are using a firewall then you must configure it to allow Designer to operate as a server, and allow Designer to communicate freely with the lighting system.

When Designer starts, it initialises itself as a client application.

When you switch to Online mode, establishes a channel through which it can communicate with the lighting system. As this channel provides a path for information to flow into and out of the computer, a firewall will normally try to prevent this taking place. For Designer to work correctly in Online mode, you must configure your firewall to allow Designer to act as a client.

Tip:

  • We recommend that you install and use a firewall and anti-virus software on each server and client computer in the lighting system. This will protect your computer from intrusions and disruptions that could have an adverse effect on the lighting system.

 

Windows 7 Firewall and Designer

 

A Windows Security Alert window may automatically pop up when Designer attempts to run on Windows 7. This may be an indication that you may need to configure the Windows firewall permissions to allow Designer to communicate freely across the network.

This is often the case when Designer is newly installed on systems, as Windows automatically flags up new, unrecognised software that is attempting to communicate freely with other computers or devices.

 

Allow Designer permission for network communication

This example uses Windows Firewall.

  1. Access Control Panel from Windows 7 desktop.

  2. Select Windows Firewall from the list.

    The Windows Firewall main window appears.

  3. Select Allow a program or feature through Windows Firewall from the list on the left of the screen.


     

  4. Scroll through to Helvar Designer and tick all boxes (Domain, Home/Work, Public)


    Note:

    • If there are multiple versions installed on your PC, click Details to check which version of Designer you are giving permissions to.

  5. Click OK to save new permissions. 

  6. Return to Desktop and run Designer.

  7. Windows Security Alert windows should no longer appear. If they do appear, tick all boxes in the window and click Allow access.
