PCM600 does not have specific firewall requirements. PCM600 is a client system from the communication point of view. However, sometimes when reading disturbance records using FTPS, for example, communication fails after some amount of successful communication. This is caused by the Windows Firewall’s Stateful Package Inspection feature. The feature can be disabled by running the following PowerShell command with administrator privileges:
Set-NetFirewallSetting -EnableStatefulFtp false -PolicyStore PersistentStore
When PCM600 is used in a distributed setup, see Distributed installation of PCM600 for actions needed on the SQL Server computer.
The firewall has to be configured manually.
