Screenshots SoftEther VPN Project develops and distributes SoftEther VPN , An Open-Source Free ​Cross-platform Multi-protocol VPN Program , as an academic project from University of Tsukuba , under the Apache License 2.0. Click here for software update history and to download the latest version SE201901: CVE-2019-11868: SoftEther VPN Server NDIS 5.x Windows Local Bridge Driver Local Privilege Escalation Vulnerability (July 9, 2019) Added the SoftEther VPN Server JSON-RPC API Suite implementation. (July 7, 2019) The API Suite allows you to easily develop your original SoftEther VPN Server management application to control the VPN Server (e.g. creating users, adding Virtual Hubs, disconnecting a specified VPN sessions) from JavaScript, TypeScript, C# or other languages. Added the Embedded HTML5-based Modern Admin Console. (July 7, 2019) Declaration of license switch for SoftEther VPN from GPLv2 to Apache License 2.0 What is SoftEther VPN SoftEther VPN ("SoftEther" means "Software Ethernet") is one of the world's most powerful and easy-to-use multi-protocol VPN software. It runs on Windows, Linux, Mac, FreeBSD and Solaris. SoftEther VPN is open source . You can use SoftEther for any personal or commercial use for free charge. SoftEther VPN is an optimum alternative to OpenVPN and Microsoft's VPN servers . SoftEther VPN has a clone-function of OpenVPN Server. You can integrate from OpenVPN to SoftEther VPN smoothly. SoftEther VPN is faster than OpenVPN . SoftEther VPN also supports Microsoft SSTP VPN for Windows Vista / 7 / 8. No more need to pay expensive charges for Windows Server license for Remote-Access VPN function. SoftEther VPN can be used to realize BYOD (Bring your own device) on your business. If you have smartphones, tablets or laptop PCs, SoftEther VPN's L2TP/IPsec server function will help you to establish a remote-access VPN from your local network. SoftEther VPN's L2TP VPN Server has strong compatible with Windows , Mac , iOS and Android . SoftEther VPN is not only an alternative VPN server to existing VPN products (OpenVPN, IPsec and MS-SSTP). SoftEther VPN has also original strong SSL-VPN protocol to penetrate any kinds of firewalls. Ultra-optimized SSL-VPN Protocol of SoftEther VPN has very fast throughput, low latency and firewall resistance. SoftEther VPN has strong resistance against firewalls than ever. Built-in NAT-traversal penetrates your network admin's troublesome firewall for overprotection. You can setup your own VPN server behind the firewall or NAT in your company, and you can reach to that VPN server in the corporate private network from your home or mobile place, without any modification of firewall settings. Any deep-packet inspection firewalls cannot detect SoftEther VPN's transport packets as a VPN tunnel, because SoftEther VPN uses Ethernet over HTTPS for camouflage. Easy to imagine, design and implement your VPN topology with SoftEther VPN. It virtualizes Ethernet by software-enumeration . SoftEther VPN Client implements Virtual Network Adapter , and SoftEther VPN Server implements Virtual Ethernet Switch . You can easily build both Remote-Access VPN and Site-to-Site VPN , as expansion of Ethernet-based L2 VPN. Of course, traditional IP-routing L3 based VPN can be built by SoftEther VPN. SoftEther VPN has strong compatibility to today's most popular VPN products among the world . It has the interoperability with OpenVPN, L2TP, IPsec, EtherIP, L2TPv3, Cisco VPN Routers and MS-SSTP VPN Clients. SoftEther VPN is the world's only VPN software which supports SSL-VPN, OpenVPN, L2TP, EtherIP, L2TPv3 and IPsec, as a single VPN software. SoftEther VPN is free software because it was developed as Daiyuu Nobori's Master Thesis research in the University. You can download and use it from today. The source-code of SoftEther VPN is available under the Apache License 2.0. Features of SoftEther VPN Free and open-source software. Easy to establish both remote-access and site-to-site VPN. SSL-VPN Tunneling on HTTPS to pass through NATs and firewalls . Revolutionary VPN over ICMP and VPN over DNS features. Resistance to highly-restricted firewall. Ethernet-bridging (L2) and IP-routing (L3) over VPN. Embedded dynamic-DNS and NAT-traversal so that no static nor fixed IP address is required. AES 256-bit and RSA 4096-bit encryptions. Sufficient security features such as logging and firewall inner VPN tunnel. 1Gbps-class high-speed throughput performance with low memory and CPU usage. Windows, Linux, Mac, Android, iPhone, iPad and Windows Mobile are supported. SSL-VPN (HTTPS) and 6 major VPN protocols ( OpenVPN , IPsec , L2TP , MS-SSTP , L2TPv3 and EtherIP ) are all supported as VPN tunneling underlay protocols. The OpenVPN clone function supports legacy OpenVPN clients. IPv4 / IPv6 dual-stack. The VPN server runs on Windows, Linux, FreeBSD, Solaris and Mac OS X . Configure All settings on GUI . Multi-languages (English, Japanese and Simplified-Chinese). No memory leaks. High quality stable codes, intended for long-term runs. We always verify that there are no memory or resource leaks before releasing the build. RADIUS / NT Domain user authentication function RSA certificate authentication function Deep-inspect packet logging function Source IP address control list function syslog transfer function More details at Specification . Architecture of SoftEther VPN Virtualization of Ethernet devices is the key of the SoftEther VPN architecture. SoftEther VPN virtualizes Ethernet devices in order to realize a flexible virtual private network for both remote-access VPN and site-to-site VPN . SoftEther VPN implements the Virtual Network Adapter program as a software-emulated traditional Ethernet network adapter. SoftEther VPN implements the Virtual Ethernet Switch program (called Virtual Hub ) as a software-emulated traditional Ethernet switch. SoftEther VPN implements VPN Session as a software-emulated Ethernet cable between the network adapter and the switch. You can create one or many Virtual Hub with SoftEther VPN on your server computer. This server computer will become a VPN server , which accepts VPN connection requests from VPN client computers. You can create one or ma...
