Consider adding host/port mapper #689
Description
Redis does not support SSL and supports external port/IP mapping only for Redis Cluster. Redis Master/Slave and Redis Sentinel report always the native Redis IP/port on which Redis runs.
This makes it impossible to use Redis topology details along with SSL or if the hosts/ports are firewalled/tunelled/proxied, …. We should provide some portmapping facility to allow optional port mapping based on host/port to rewrite Redis details.
This would be required for Redis Master/Slave with topology discovery using Redis Sentinel or via INFO REPLICATION.
