Many home and business privateWith many business networks as some home networks, company networks are separated from the Internet by a network gateway device such as a NAT (IP masquerading),measures such as NAT (IP masquerade) proxy servers and firewalls. These gateway devices may be a dedicated device (appliance) or a high performance computer running Linux etc. The gateway device performs both security functions as well as limiting the number of actual Internet addresses needed to connect the private network to the Internet, number of IP addresses is limited and security is bolstered. Devices that conduct this processing are called network gateway devices. In some cases network gateway device is a dedicated device (appliance) and in some cases is a high-performance computer on which Linux, etc., is installed.
However many older VPN protocols cannot communicate via this network gateway device. One reason for this is many VPN protocols use special headers when encapsulating communications packets that are not part ofheadersof special protocol that is not ordinary TCP/IP protocol may be added when encapsulating communications packets. For example a VPN protocol called PPTP uses an extremely minor protocol called Generic Routing Encapsulation (GRE). A VPN protocol called L2TP furthermore requires use of IPSec, whereby a header is added because it is an IPSec packet.
The result of using non-standard TCP/IP such as mentioned in the examples is that traditional VPN communications are prevented by, or at least impose the need for configuration changes to, most network gateway devices (NAT, proxy majority of conventional VPN protocols such as in these examples, because VPN communications is realized by an approach unlike ordinary TCP/IP connection-oriented communication model, it cannot carry out VPN communications transcending in many network gateway devices, especially NAT (IP masquerade), almost all proxy servers and firewalls.

Using SoftEther VPN, the user creates a highly flexible, secure tunnel based on the widely available and easy TCP/IP protocol, and by connecting the tunnel called SoftEther VPN protocol based on TCP/IP protocol among them, the user can construct highly flexible VPN that was never possible with products up to now.
