Internal Outgoing and Incoming Connections
To ensure the NFS cluster internal communications, set up the firewall configuration with the following ports open:
| From | To | Protocol | Port |
|---|---|---|---|

Note: Each of the NFS servers has its own fencing device. Depending on the device type, you may need to perform additional firewall configuration for NFS servers and the quorum server to establish connection between them and the STONITH devices. Primary NFS server should have access to the STONITH device controlling the Secondary server, and vice versa.
