 RDP Shortpath is a feature of Azure Virtual Desktop that establishes a direct UDP-based transport between a supported Windows Remote Desktop client and session host. This article shows you how to configure RDP Shortpath for managed networks and public networks. For more information, see [RDP Shortpath](rdp-shortpath.md).

 The transport used for RDP Shortpath is based on the [Universal Rate Control Protocol (URCP)](https://www.microsoft.com/research/publication/urcp-universal-rate-control-protocol-for-real-time-communication-applications/). URCP enhances UDP with active monitoring of the network conditions and provides fair and full link utilization. URCP operates at low delay and loss levels as needed.

-Each RDP session uses a dynamically assigned UDP port from an ephemeral port range (**49152** to **65535** by default) that accepts the RDP Shortpath traffic. You can also use a smaller, predictable port range. For more information, see [Limit the port range used by clients for public networks](configure-rdp-shortpath-limit-ports-public-networks.md).
+Each RDP session uses a dynamically assigned UDP port from an ephemeral port range (**49152** to **65535** by default) that accepts the RDP Shortpath traffic. Port 65330 is ignored from this range as it is reserved for use internally by Azure. You can also use a smaller, predictable port range.

 > [!TIP]
 > RDP Shortpath for public networks will work automatically without any additional configuration, providing networks and firewalls allow the traffic through and RDP transport settings in the Windows operating system for session hosts and clients are using their default values.
