The device that does the xxx.xxx.xxx.xxx <=> yyy.yyy.yyy.yyy
translation needs to be configured to translate incoming (from the
Internet) TCP connections to xxx.xxx.xxx.xxx:5432 to yyy.yyy.yyy.yyy:5432
(substitute 5432 with whatever port(s) you're using for PostgreSQL;
5432 is the default). In addition to the translation the device
might also need a firewall rule to allow those inbound connections.
I'd recommend using as restrictive a filter as possible -- if only
one or a handful of hosts need access to the database then allow
only those hosts to connect. You might also consider allowing or
even requiring SSL connections ("hostssl" in pg_hba.conf), possibly
with SSL client authentication.
What kind of device is doing your address translation? Somebody
here has probably used whatever you're using and might be able to
provide specific instructions or commands.
