Subject Re: multiple nodes sharing the same IP

storage_port: Used for Gossip and Data exchange. So in your word, it
is the port for the seeds.

You CAN change the storage_port, but all nodes in your ring need to
use same storage_port number.
That's why you need different IP address for each node.

rpc_port: Used for Thrift which the Cassandra clients connect to.

I can't understand why you can't change rpc_port.
