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.

• 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.
