Hello Sergey, Currently Cassandra listens in one interface (the listen_address), so you can only use multiple interfaces if your NAT configuration can route from your public IP address to your private interface, as typically happens on EC2 and other clouds. We're currently working to support listening on multiple network interfaces to support this use case. You can follow the progress and get more background on this ticket: https://issues.apache.org/jira/browse/CASSANDRA-9748. There's a preliminary patch available if you're willing to patch your Cassandra install.
