I have configured a dynomite (proxy) cluster of three nodes. The cluster is up and running, but when i try to connect to a redis instance via any node in the cluster, i get the following error after running this command:

Ubuntu@ redis-1:~$redis-cli -h 192.168.1.195 -p 8102 ping

Error: Connection reset by peer

Ubuntu@ redis-1:~$

But when i try to connect to the same remote Redis server directly via the default Redis port, 6379, the command works just fine as shown below:

Ubuntu@ redis-1:~$redis-cli -h 192.168.1.195 -p 6379 ping

PONG

Ubuntu@ redis-1:~$

Here is my architecture:

Three dynomite nodes in the cluster:

dynomite-1: 192.168.2.190

dynomite-2: 192.168.2.191

dynomite-3: 192.168.2.192

Remote connection is being performed on a fourth Redis server (not part of the dynomite cluster):
