AWS – Amazon WorkSpaces WSP enables desktop traffic over TCP/UDP port 443

Amazon WorkSpaces Amazon DCV-enabled desktop traffic now supports both TCP and UDP over Port 443. This feature will be used automatically, requiring no configuration changes. Customers using port 4195 can continue to do so. The WorkSpaces client application prioritizes UDP (QUIC) for optimal performance, but will fallback to TCP if UDP is blocked. The WorkSpaces web client will connect over either TCP Port 4195 or 443. If Port 4195 is blocked, the client will exclusively use port 443.

Organizations managing WorkSpaces may not be the same as the organization managing the client networks where users will connect to WorkSpaces. Each network is managed independently, creating administration challenges, delays, or roadblocks to change outbound access rules. By opening WorkSpaces DCV desktop traffic over TCP/UDP Port 443 with support for fallback to TCP if UDP is not available, customers no longer need to open TCP/UDP 4195 unique ports.

WorkSpaces DCV enabled desktop traffic over TCP/UDP Port 443 support is available in all AWS Regions where Amazon WorkSpaces is available. There is no additional charge for this feature. Please see the Amazon WorkSpaces Administration Guide for more information.
