That is basic SolrCloud operation.

If the nodes cannot communicate with each other, they cannot keep
replicas in sync, they will not know when another node goes down
(required to keep the clusterstate current), multi-shard distributed
search will not work, Solr cannot load balance queries across the cloud,
collection creation will not work, and so on.  There are probably
several other fundamental SolrCloud operations that require inter-node

If you don't want the nodes to talk to each other, you probably need to
stop using SolrCloud, plus give up distributed search and replication
