Default Ports For Nodes

Here is a list of default ports used across Polygon nodes:

Bor

Name	Port	Tags	description
Network listening port	30303	public	Network listening port. Bor uses this port to connect to peers and sync
RPC server	8545	can-be-public, internal	RPC port to send transaction and get data from Bor. Heimdall uses this port to get Bor headers for checkpoints
WS server	8546	can-be-public, internal	Websocket port
Graphql server	8547	can-be-public, internal	Graphql port
Prometheus server	9091	can-be-public, monitoring	Prometheus server APIs as datasource in Grafana. It can be mapped to 80/443 through nginx reverse proxy
Grafana server	3001	can-be-public, monitoring	Grafana web sever. It can be mapped to 80/443 through nginx reverse proxy
Pprof server	7071	internal, monitoring	Pprof server to collect metrics from Bor
UDP discovery	30301	can-be-public, internal	Bootnode default port (for peer discovery)
