Cassandra Firewall Ports
Cassandra uses various ports for communication, either server to server communication or client to server communication.
If you’re using Cassandra in a firewalled environment you may need to open various ports depending on your needs. All ports are TCP and can be configured in the relevant config files to use non-default ports.
|7000||TCP||Non-encrypted inter-node cluster communication. Not used if SSL is in use.|
|7001||TCP||Encrypted SSL inter-node cluster communication. Not used if SSL is not in use.|
|7199||TCP||JMX monitoring port.|
|9042||TCP||Client port used for native CQL.|
|9160||TCP||Client port used for Thrift.|
