Hi, A few comments as I read:
> I'm using node0 as seeder It is recommended to use at least 2 nodes per DC as seeds, for fault tolerance and good gossip propagation. Also I think you are a bit confused about what a seed node is and is not. See: https://docs.datastax.com/en/cassandra/2.1/cassandra/architecture/architectureGossipAbout_c.html I want to use the node0 as seeder and use the public ip so that i can > access it remotely and can join with other Datacenter nodes later time. But > my rest of the nodes should not have any public interfaces. Now how to > configure it? This does not look right to me. All the nodes must receive the same operational care. It is a lot easier to reason about an homogeneous cluster and I do not recommend this kind of approaches at all. To use public IP on a node, set the broadcast_address to public IP, and make sure ports are open on whatever IP address you are trying to connect to. Sorry for the month delay, hope this is still useful.
