Postgres replication question :- One master 2 slaves 9.0.10

        Currently we have set up one master one slave , which working fine.  Now we need to replicate to an other slave.  The problem  we have , the port that we use on primary can not be reached from the new slave.  We can't the change the primary port also, because many applications using it.

          I can't reach out to my primary using the recovery.conf on the new slave.
