Global Secure Access connector guidance adds separate dynamic and AutoReuse TCP ranges

Two Global Secure Access documentation updates sharpen connector port guidance. The Connectors page specifies non-overlapping dynamic TCP ports 49152–65535 and AutoReuse TCP ports 10000–49151, adds configuration and verification commands, and documents Windows Server 2016+ prerequisites. The configuration page now discusses dynamic and AutoReuse TCP ranges instead of extending TCP and UDP ephemeral ports.

  Connectors guidance specifies port ranges, prerequisites, and verification commands

  The documentation defines dynamic TCP ports as 49152–65535 and AutoReuse TCP ports as 10000–49151. The ranges must not overlap; the update also adds configuration and verification commands, Windows Server 2016+ prerequisites, and the limitation that AutoReuse applies only to TCP.

  Configuration guidance replaces ephemeral-port extension with TCP range configuration

  The connector configuration page now refers to configuring dynamic and AutoReuse TCP port ranges rather than extending TCP and UDP ephemeral ports, changing the performance and scalability procedure administrators should follow.
