what changes are required on Solace VPN to connect to Kafka Connector.

Hi @Ankur lodhi,

If you're using the new kafka bridge that is built into our brokers you can find how to configure it in the docs: https://docs.solace.com/Features/Kafka-Bridging/Kafka-Bridging-Overview.htm

And if you're using the external ones you can find info on the connector hub:

https://solace.com/connectors/?fwp_connectors_search=kafka

Please feel free to follow-up if you have any follow-up questions!
