Sono incappato nella tesi di laurea di tal Nobori, che non avendo di meglio da fare, ha sviluppato il software definitivo per le VPN. Sia in versione client che server.
Con l’opportuna disponibilità di una piccolo vps sperduto in una server farm nell’europa centrale (ogni riferimento a siti o persone è assolutamente volontario) si riesce a bucare praticamente qualsiasi firewall aziendale mantenendo la disponibilità di banda praticamente inalterata e garantendo allo stesso tempo un elevatissimo livello di privacy.
Anche con firewall con Deep Packet Inspection il traffico risulterebbe non differente da normali trasferimenti HTTPS.
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.
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.
