Can I Modify the Port for Accessing a Kafka Instance?

No. You must access a Kafka instance through one of the following ports:

• Accessing a Kafka instance without SASL:

  The port varies with the access mode:

  • Intra-VPC access: port 9092
  • Public access: port 9094
  • Cross-VPC access using a VPC endpoint: port 9011
  • Cross-VPC access using a peering connection: port: 9092.
  • DNAT access: port 9011
• Accessing a Kafka instance with SASL:

  The port varies with the access mode:

  • Intra-VPC access: port 9093
  • Public access: port 9095
  • Cross-VPC access using a VPC endpoint: port 9011
  • Cross-VPC access using a peering connection: port: 9093.
  • DNAT access: port 9011

Ensure that proper rules have been configured for the security group of the instance. For details, see How Do I Select and Configure a Security Group?
