Manage Firewall Rules
You can review, modify, and manage the firewall rules that are in effect on the system. MiniCluster primary administrators use the Firewall Manager to stop or start the Solaris firewall services on demand, and can make changes to ports, protocols, and services in the existing firewall rules applied to MiniCluster's virtual hosts.
The preconfigured Firewall Manager is enabled by default in MiniCluster version 1.2 and later.
Only experienced administrators should edit the firewall rules. To learn about firewall rules and how to edit them, refer to one of the following Oracle Solaris Documents:.
-
Oracle Solaris 11.4– Configuring the Firewall in Oracle Solaris
-
Oracle Solaris 11.3– IP Filter Firewall in Oracle Solaris
-
Log into the MCMU as a primary administrator, such as
mcinstall.
Only the primary administrator can make changes to firewall rules. For login instructions, refer to Accessing the System in Oracle MiniCluster S7-2 Administration Guide.
- In the navigation panel, select System Settings → Firewall Manager.
- Choose the node and virtual machine host name that you want to modify.
- In the Firewall Rules Editor section, edit the existing rules.
-
Click Apply Changes to save the firewall configuration.
The Solaris firewall configuration is saved for this host. Some changes take time while the correct information is gathered and displayed.
Caution - The Firewall Rules Editor does not check for proper syntax.
- Click Disable (or Stop) to disable the firewall services for this host.
-
Click Start to enable the firewall services for this host.
You must restart the firewall for the changes to take effect. The Status changes from disabled to online. You can also use the CLI to verify firewall rules. For instructions, see Verify Firewall Rules.
