Configuring network rules
On this page
To further lock down the communication in between the nodes in your SonarQube Server cluster, you can define the network rules. The setup depends on the installation type.
| Protocol | Source | Destination | Port | Default |
|---|---|---|---|---|
| TCP | Reverse Proxy | App Node | sonar.web.port | 9000 |
| TCP | App Node | Search Node | sonar.cluster.node.search.port | 9001 |
| TCP | Search Node | Search Node | sonar.cluster.node.es.port | 9002 |
| TCP | App Node | App Node | sonar.cluster.node.port | 9003 |
You can further segment your network configuration if you specify a frontend, a backend and a search network:
| Network | Parameter | Description |
|---|---|---|
| Frontend | sonar.web.host | Frontend HTTP Network |
| Backend | sonar.cluster.node.host | Backend App to App Network |
| Backend | sonar.cluster.search.hosts | Backend App to Search Network |
| Search | sonar.cluster.node.search.host | Backend Search to Search Network |
For information about the parameters, see the list of system properties specific to the Data Center Edition.
