Hi team,

I have a ELK Stack with _ **2 Logstash Nodes in DataCentre1** _ and a **Kafka Cluster in another DataCentre2** accepting log events from servers in DataCentre2 .

_SitetoSite VPN connects the DC1 to DC2._  
_Telnet from Kafka cluster (Source) in DC2 to Logstash machines(Destination) in DC1 is enabled._  
_And kafka cluster is receiving messages from filebeats in DC2 (verified with Kafdrop)_

But logstash is not receiving or consuming the messages.  
Please help if any network related config miss is blocking messages from Kafka to logstash
