Hello Tom, Thanks for the reply. So in other words, the postgres clients do not use a specific range for the source port (as a specific decision by the developers, or as written down in a given spec), but rather relies on the operating system's socket implementation to assign a source port? So in practice the source port can be any non-privileged port (from postgreses point of view)? I only ask this clarification to be sure to pass on the correct info on to the administrator of the firewall...
