------------------------------------------

             Summary:  Multiple Network Interfaces in non-EC2
                 Key: CASSANDRA-12631
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12631

          Components: Core
         Environment: RHEL6
Node1 external: 10.240.33.241
Node1 internal: 192.168.33.241
Node2 external: 10.240.33.244
Node2 internal: 192.168.33.244
 
cassandra-rackdc.properties (for both nodes) also tried with prefer_local=false:
dc=vdra015-xs-15
rack=rack1
prefer_local=true

listen_on_broadcast_address: true
rpc_address: 192.168.33.241 or 192.168.33.244
endpoint_snitch: GossipingPropertyFileSnitch
 
Routing table:
# ip r

Summary: Unable to connect to seed node (other than self)

Experienced behavior:
1.       Node1 starts up normally
# netstat -anlp|grep java
tcp        0      0 127.0.0.1:55452             0.0.0.0:*                   LISTEN      10036/java
tcp        0      0 127.0.0.1:7199              0.0.0.0:*                   LISTEN      10036/java
tcp        0      0 10.240.33.241:7000          0.0.0.0:*                   LISTEN      10036/java
tcp        0      0 192.168.33.241:7000         0.0.0.0:*                   LISTEN      10036/java
tcp        0      0 ::ffff:192.168.33.241:9042  :::*                        LISTEN      10036/java
2.       When I try to start node2, it is unable to connect to node1 IP set in seeds
Exception (java.lang.RuntimeException) encountered during startup: Unable to gossip with any
seeds
java.lang.RuntimeException: Unable to gossip with any seeds
3.       Running tcpdumpon node2, I can see that node2 is trying to connect to node1 external
IP but with its source internal IP
# tcpdump -nn -i eth0 port 7000
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes

4.       Running tcpdump on node1, shows packets are not arriving
