PowerScale OneFS 9.8.0.0 Web Administration Guide

Firewall and ports

Global firewall policies contain rules for the OneFS default ports on all services. If your installation changes port settings, you must customize policies.

Some OneFS services allow administrators to modify the ports on which the service daemon listens. The service ports can be changed before and after the firewall is enabled. In either case, administrators must also update firewall policies when changing ports.

For example, the OneFS system default for ssh is port 22. Administrators can use the isi ssh settings modify command to change that port setting. If the port is changed, the firewall rules that are intended for that port are no longer applicable.

WARNING:The firewall policies do not automatically update when you reconfigure ports. This caveat applies to both global and custom policies.
