SoftEther VPN
SoftEther VPN is free open-source, cross-platform, multi-protocol VPN client and VPN server software, developed as part of Daiyuu Nobori's master's thesis research at the University of Tsukuba. VPN protocols such as SSL VPN, L2TP/IPsec, OpenVPN, and Microsoft Secure Socket Tunneling Protocol are provided in a single VPN server. It was released using the GPLv2 license on January 4, 2014. The license was switched to Apache License 2.0 on January 21, 2019.

SoftEther VPN supports NAT traversal, making it useful to run VPN servers on computers that are behind residential gateways, facility routers, and firewalls. Firewalls performing deep packet inspection are unable to detect SoftEther's VPN transport packets as a VPN tunnel because HTTPS is used to camouflage the connection.
SoftEther VPN optimizes performance by using full Ethernet frame utilization, reducing memory copy operations, parallel transmission, and clustering. Together, these reduce latency normally associated with VPN connections while increasing throughput.
