Firewall and VPN Settings


Firewalls can block GigE Vision packets and slow down the system performance.

Therefore it is important to disable all firewalls within the camera connection setup when there are connection problems.


The following steps are necessary to switch off the Windows software firewall. For Linux there is no configuration necessary.

If you have a hardware firewall (which is available on some NICs) disable those firewalls also.


Also any VPN software running on the system may contain a "Stateful Firewall" which is active even if no tunnel is established.

This firewall will block traffic from the camera.

In order to work with GEV devices and depending on the VPN software you use, you have to disable your VPN software.


Windows only:


1. Open the Firewall Customize Settings dialog (Start -> Control Panel -> Systems and Security -> Windows Firewall -> Turn Windows Firewall on or off) :




2. Select the "Turn Off Windows Firewall" option to disable the firewall for the type of network which is used for the camera connection.


3. Close all dialogs with the "OK" button to apply the changes.
