             Summary: Can't see other nodes when using multiple network interfaces
                 Key: CASSANDRA-9748
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9748
             Project: Cassandra
          Issue Type: Bug
         Environment: Cassandra 2.0.16; multi-DC configuration
            Reporter: Roman Bielik


The idea is to setup a multi-DC environment across 2 different networks based on the following configuration recommendations:
http://docs.datastax.com/en/cassandra/2.0/cassandra/configuration/configMultiNetworks.html

Each node has 2 network interfaces. One used as a private network (DC1: 10.0.1.x and DC2: 10.0.2.x). The second one a "public" network where all nodes can see each other (this one has a higher latency). 

Using the following settings in cassandra.yaml:

*seeds:* public IP (same as used in broadcast_address)
*listen_address:* private IP
*broadcast_address:* public IP
*rpc_address:* 0.0.0.0
*endpoint_snitch:* GossipingPropertyFileSnitch
_(tried different combinations with no luck)_

No firewall and no SSL/encryption used.

The problem is that nodes do not see each other (a gossip problem I guess). The nodetool ring/status shows only the local node but not the other ones (even from the same DC).
When I set listen_address to public IP, then everything works fine, but that is not the required configuration.

_Note: Not using EC2 cloud!_
