Starting and stopping firewall instances is performed automatically using the default installation. However, it is possible to control manually the firewall instances with the velactl utility. velactl starts and stops PNS instances using the instances.conf file. One or more instance names can be passed to velactl as arguments. If an error occurs while starting or stopping one of them, an exclamation mark ('?') is appended to the name of the instance as the script processes requests.

To control Application-level Gateway with velactl, enter the following lines.

velactl start|stop <instance name> <instance name> <...>

Besides the start and stop parameters for controlling instances, velactl has some other parameters as well.

For a full list of the available parameters with short explanations type velactl at a command prompt, without parameters, or issue the man velactl command. The manual page of velactl is also available at velactl(8) in Proxedo Network Security Suite 2 Reference Guide.
