CKafka currently does not support public network access.
How do I continue accessing CKafka over VPC after SASL is enabled?
If you use the PLAINTEXT method to access CKafka while enabling another SASL access routing, the ACL previously set for the topics will still take effect. If you want PLAINTEXT access to be unaffected, please add the read/write permissions of all users for the topics that PLAINTEXT needs to access.
Note:
When adding an ACL policy, you don't need to select any user, and read/write permissions are added to all users by default.
