During the configuration a few ports on appliance are open. You can view the current firewall configuration from the ZENworks Appliance.
On the ZENworks Appliance home page, in the Appliance Configuration section, click
Port numbers are displayed with the current status.
If you have a firewall, you must allow the listed port numbers to ensure that you have a seamless experience with ZENworks Appliance. As a best practice, do not change any port numbers from the default ports.
For more information on opening the Firewall ports, see the Opening Ports section in the SUSE Linux Enterprise Server Documentation.
