Firewall Rules for Forest Server Backups
The following firewall settings are required for communicating with Recovery for Active Directory and the domain controller when executing a domain controller backup. The firewall rules must be configured on both the domain controller and the application server.
| Communication Direction | Protocol | Ports | Description |
|---|---|---|---|
| Domain Controller to Application Server | TCP | 9001 | Outbound Communication |
| Application Server to Domain Controller | TCP | 9001 | Inbound Communication |
NOTE: 9001 is the default port. If a different port is specified on the Netwrix Recovery Server Configuration page of the Recovery for Active Directory Setup wizard while installing the application, then that specific port is applicable here.
