With this patch, start two nodes node 1: scylla --rpc-address 127.0.0.1 --broadcast-rpc-address 127.0.0.11 node 2: scylla --rpc-address 127.0.0.2 --broadcast-rpc-address 127.0.0.12 On node 1: cqlsh> SELECT rpc_address from system.peers; rpc_address ------------- 127.0.0.12 which means client should use this address to connect node 2 for cql and thrift protocol.
