Global Secure Access connector guidance now specifies non-overlapping TCP port ranges

Two updated Global Secure Access pages refine connector TCP configuration. The guidance specifies dynamic TCP ports 49152–65535 and AutoReuse TCP ports 10000–49151, adds configuration and verification commands, and documents Windows Server 2016+ prerequisites. AutoReuse applies only to TCP.

For Entra administrators

Administrators supporting high-volume TCP workloads should review connector server prerequisites, configure the documented ranges without overlap, and use the new verification commands. The performance guidance now focuses on dynamic and AutoReuse TCP ranges rather than extending TCP and UDP ephemeral ports.
