Local Firewall Greenbone Enterprise

Does anyone know how to configure the local firewall on the Greenbone Enterprise OS?
We would either like to configure the firewall or get access to the cli of the OS, when we SSH into the box. The only thing getting up when we SSH is the Enterprise Wizard which we cannot configure the local firewall in.

We are usingthe Virtual appliance in an VMware environment.

Don´t do that, most use a dedicated management interface so no services are reachable on the scan interface.

If you setup a firewall, you can end in something called session tracking and ruin your scan results / time.
