SSTP Connect is a VPN client that supports these protocols: - SSTP (MS-SSTP) - SoftEther VPN This is only a VPN client. No VPN service is included. You need to specify the server you are connecting to. • Native Only iOS native libraries are used in the core function, including the TLS stack. No OpenSSL. Connections are saved natively so that you can start a connection from the system settings. • Simple VPN clients ought to be small and simple. No ads, analytics or other 3rd-party SDK are included. • Privacy No data is collected from you. Connection log only exists in the memory and is never saved to the device. • Complete Support all password and certificate-based authentications available in Windows 11. Support authenticating by password and certificate at the same time with TEAP (EAP chaining). Protocol details below. • Security Passwords and certificates are stored in the iOS keychain.

(DHCPv6 not supported) • More than TCP Support NAT traversal (NAT-T) and UDP acceleration just like the official SoftEther client. • Easy Import and Export Not only from SSTP Connect, reading connection settings from SoftEther Client Manager is also a piece of cake. • Routing Accept static routes pushed from the server or add your own entries. SSTP Authentication Methods - PEAP - EAP-TTLS - TEAP (EAP chaining) - EAP-TLS - EAP-MSCHAPv2 - MSCHAPv2 - CHAP - PAP SoftEther Authentication Methods - Password - RADIUS / NT Domain Password - Certificate - Anonymous Supported Server Platforms • Microsoft Windows Server 2008 and later • Microsoft Azure P2S VPN • MikroTik RouterOS* • SoftEther VPN Server • VPN Azure * Servers configured without certificates are not supported.
