Till Rohrmann updated FLINK-16751:
----------------------------------
Description:
With FLINK-15911 it is now possible to run Flink behind a NAT/with an
unresolvable external address. However, due to FLINK-11127, the
{{MetricFetcherImpl}} tries to connect to the {{TaskManagers}} instead of the
other way around. If the TM is running behind a NAT, it would require to define
an external port. At the moment, it is only possible to configure the bind port
via {{metrics.internal.query-service.port}}. Hence, the external port always
needs to be the same as the bind port if port forwarding should work.
I think in order to properly solve this problem we either solve FLINK-11127 or
we introduce a {{metrics.internal.query-service.bind-port}} option which allows
to configure a bind port. With such an option,
{{metrics.internal.query-service.port}} would become the external port.
