I have both these entries on the pg_hba.conf Master server:
host replication all 192.168.127.6/32 trust
host all all 192.168.127.6/32 trust
and still cannot get replication to start.
I can make normal postgresql database connections fine to the master
database from the slave with these pg_hba.conf settings, so it is surely
not a firewall issue.
