Migrate a privileged Splunk Phantom deployment to an unprivileged deployment

End of support for iptables

Splunk Phantom 4.10.0 is the final release that supports iptables. Both Red Hat Enterprise Linux 7 and CentOS 7 and later releases use firewalld as their default managed firewall. Splunk Phantom scripts and tools in future releases will only support firewalld.

Customers are encouraged to migrate to firewalld to use with future releases of Splunk Phantom.

CentOS 6 and Red Hat Enterprise Linux 6 are no longer supported

As announced in the release notes for Splunk Phantom 4.9, Splunk Phantom 4.10.0 has removed support for CentOS version 6 and Red Hat Enterprise Linux version 6. Both CentOS 6 and Red Hat Enterprise Linux reached End of Life status on November 30, 2020.

Customers are encouraged to migrate to CentOS 7 or Red Hat Enterprise Linux 7 or newer in order to use Splunk Phantom 4.10.0 and future releases of Splunk Phantom. For assistance on migrating to a supported operating system, see Migrate a Splunk Phantom install from REHL 6 or CentOS 6 to RHEL 7 or CentOS 7 in Install and Upgrade Splunk Phantom.
