Restricting TCP connections.
I have two tomcat servers SrvA & SrvB and two couchbase base server CB1 & CB2. Thus, I have 4 physical machines on network. CB1 and CB2 are configured in cluster mode. I want some option within couchbase server such that only my tomcat servers SrvA with IP address X and SrvB with IP address Y can access couchbase server nodes / clusters. NO other machines can connect to couchbase ports.
