SoftEther VPN Client for Windows

SoftEther VPN is a powerful and user-friendly VPN software that supports many operating systems like Windows, Linux, Mac, FreeBSD, and Solaris. Developed as part of Daiyuu Nobori's Master Thesis at the University of Tsukuba, it is open-source and free for both personal and commercial usage.

SoftEther VPN functions primarily as a VPN client but also encompasses capabilities typical of VPN servers, offering features that facilitate both remote-access and site-to-site VPN configurations. It is a formidable alternative to conventional VPN solutions like OpenVPN and Microsoft’s VPN servers, providing enhanced speed and compatibility with a range of VPN protocols including SSL-VPN, L2TP, IPsec, and more.

The client is equipped with a GUI that simplifies the configuration and management of VPN connections. Users can easily set up a VPN, switch between different VPN protocols, and manage connections all through intuitive menu options and clear, descriptive layouts.

SoftEther supports many VPN protocols. This versatility ensures that users can easily switch from other VPNs to SoftEther and integrate it into any network environment. It also supports both IPv4 and IPv6, making it adaptable for all types of network setups.

SoftEther provides strong security features like AES 256-bit and RSA 4096-bit encryption to keep your data safe. It’s excellent at getting through NATs and firewalls using special techniques like VPN over ICMP and DNS. The software also comes with dynamic DNS and NAT traversal, removing the need for a static IP address when setting up a VPN server.

The client’s standout features include Ethernet-bridging and the ability to support complex network configurations. This flexibility is ideal for everything from personal VPN use to managing large, corporate networks.

SoftEther is free and open-source, available under the Apache License 2.0. You can download it from the SoftEther website, where you'll also find helpful guides and documentation. This VPN client is recommended for anyone from IT professionals who need robust networking solutions to individuals wanting a secure, private internet connection on multiple devices.
