The firewall technology provided by MiniCluster differs based on the version of the Oracle Solaris OS that is running on MiniCluster components.
MiniCluster 1.3.0 and later
MiniCluster now uses the packet filter functionality delivered by Oracle Solaris 11.4 to enable network traffic protection. This enables MiniCluster to protect networks and virtual hosts from network-based intrusions. Packet Filtering is enabled and disabled through the use of the SMF service svc:/network/firewall for Global and Kernel Zones, and all VMs running Oracle Solaris 11.4.
The Firewall Manager feature is available through the MiniCluster BUI (System Settings → Firewall Manager).
MiniCluster 1.2.5.22 and earlier
MiniCluster provides network traffic protection using Oracle Solaris 11.3 IP Filter-based firewalls for virtual machines, including global, non-global, and kernel zones.
For instruction on updating firewall rules, refer to Manage Firewall Rules in Oracle MiniCluster S7-2 Security Guide.
