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. SSTP Connect never saves them locally for convenience.

• IPv6 Ready
Support both IPv6 connections and stateless IPv6 configuration in the VPN tunnels. (DHCPv6 not supported)

• More than TCP
Support NAT traversal (NAT-T) and UDP acceleration just like the official SoftEther client. (Requiring iOS 12+)

• 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.
