Starting and stopping firewall instances is performed automatically using the default installation. However, you can control manually the firewall instances with the zorpctl utility. Zorpctl starts and stops PNS instances using the instances.conf file. One or more instance names can be passed to zorpctl 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 zorpctl, enter the following lines.

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

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

For a full list of the available parameters with short explanations type zorpctl at a command prompt, without parameters, or issue the man zorpctl command. The manual page of zorpctl is also available at zorpctl(8) in Proxedo Network Security Suite 1.0 Reference Guide.
