We are trying to replicate data from ServiceNow to our local Kafka servers. We are using Stream Connect message replication through mid server. 

Does mid server connects Hermes Kafka through standard Kafka protocol (direct connection) or other mechanism like Kafka Rest API?

Our mid server is behind a firewall in a local network. Since proxy is not supported by standard Kafka, how can we connect Hermes Kafka from our local network?

Depending how you are connecting to Kafka, tie it to a MID Server

If you can connect directly to the Kafka database below is an example Data Source.

Notice the "Type" and "Use MID Server" fields

Or if setting up a REST Message record in the Platform Web Service module the MID server can be set via script

Platform Web Service example:

Or if using a REST Step in Flow Designer make sure to check the "Use MID" field

Thanks for the reply. I think it's different. We are using the OOB Stream Connect Message Replication of Servicenow.  I believe the connection between Mid Server and Stream Connect Hermes Kafka is implemented by a MIDExtension - MessageReplicationExtension implemented by ServiceNow, which is transparent to end users.
