We are in a situation where we need Cassandra nodes to be accessible from an external IP, but there is no interface with that IP; traffic to that IP is NATted to the node. Per DataStax's documentation, we have set listen_address to the internal IP and broadcast_address to the external IP. Nodes are able to connect to each other and gossip successfully; all is well except on our nodes enabled for search. On those nodes, when the Solr container is activated, we get:
java.io.IOError: java.net.BindException: Cannot assign requested address

Testing different configurations seems to indicate that Netty is attempting to listen on the broadcast_address. How can we configure it to do otherwise? dse.yaml exposes an option to change the port, but not the host.
Many thanks for your help.
