description SoftEther VPN Overview
Developed as open-source VPN software, SoftEther VPN supports several connection protocols within one server system. These include its SSL/TLS-based VPN protocol as well as L2TP/IPsec, OpenVPN-compatible connections, and Microsoft SSTP. That flexibility helps administrators connect clients with different protocol requirements instead of designing a network around a single option. SoftEther suits self-hosted remote access and connections between separate networks, including academic or research environments with mixed systems.
Server support includes Windows, Linux, and macOS, although operating-system support differs between components. Mobile devices can connect using compatible VPN protocols; this does not mean every device runs a native SoftEther client. Its distinguishing feature is configurable protocol compatibility, with administration and maintenance handled by the organization running it.
help SoftEther VPN FAQ
What protocols does SoftEther VPN support?
SoftEther VPN is uniquely designed as a multi-protocol server that natively supports OpenVPN, L2TP/IPsec, SSTP, and its own proprietary SSL-VPN protocol. This allows a single SoftEther server to accept connections from almost any built-in mobile or desktop VPN client.
Is SoftEther VPN free to use?
Yes, SoftEther VPN is completely free and open-source software. It was originally developed by the University of Tsukuba in Japan as an academic research project and remains free for both personal and commercial enterprise use.
How does SoftEther VPN bypass strict firewalls?
SoftEther uses HTTPS over TCP port 443, which is the standard port used for regular secure web traffic. Because blocking this port would break most of the internet, Deep Packet Inspection (DPI) firewalls struggle to identify and block SoftEther traffic without causing massive collateral damage.
What operating systems can run SoftEther VPN?
The SoftEther VPN Server, Client, and Bridge software are available for Windows, Linux, macOS, and Solaris operating systems. This cross-platform compatibility makes it a highly versatile solution for building both personal and enterprise VPN networks.
