Retirement: Azure VPN Gateway support for SSTP Protocol will be retired on March 31, 2027

Due to its limited scalability and suboptimal performance, support for SSTP will be phased out. We strongly recommend transitioning to IKEv2 or OpenVPN, which offer significantly enhanced capabilities—including support for up to 10,000 connections and 10 Gbps aggregate throughput, depending on your gateway SKU.  

Key dates: 

• Mar 31, 2026: Enabling SSTP protocol on VPN gateway will no longer be supported 
• Mar 31, 2027: Existing SSTP-enabled gateways can no longer be used to establish SSTP connections. 

Required action

To avoid service disruptions, please follow the instructions to migrate to IKEv2 or OpenVPN before March 31, 2027.
