If I understand you correctly, you want prefer_local to affect the local node
as well and not always use local IP?
I have also tried to use prefer_local, it only affects the peers not the
messaging to node itself.
I've tested Cassandra 4 with my patch and now it works correctly, previously
ranged queries and other communication within node through messaging did not
work (because the pod behind LB cannot connect to itself through LB).

I have also tried to use prefer_local despite the ticket you linked, it only
affects the peers not the messaging to node itself.
Btw, I've tested Cassandra 4 with my patch and now it works correctly,
previously ranged queries and other communication within node through messaging
did not work (because the pod behind LB cannot connect to itself through LB).

> During testing of Cassandra on AWS, we noticed some behavior changes between
> Cassandra 3.11 and Cassandra 4.0 when it comes to messaging.
> When performing a range query with consistency local_quorum, Cassandra sents
> a request to itself and some peers.
> In case of Cassandra 4.0, it's trying to connect to itself using the
> broadcast_address while in Cassandra 3.11 it's connecting using the local
> address (see
> [https://github.com/apache/cassandra/blob/cassandra-3.11/src/java/org/apache/cassandra/net/OutboundTcpConnectionPool.java#L152].
> This translation seems to be missing in Cassandra 4.X. I think the best place
> to fix it would be here (see attached file):
> [https://github.com/apache/cassandra/blob/cassandra-4.0/src/java/org/apache/cassandra/net/OutboundConnectionSettings.java#L451]
