    This section contains a description of operation principle and communication method of VPN that can be constructed by SoftEther VPN, an overview of the modules and functions that was used by VPN communications and the types of VPN that can be constructed using SoftEther VPN.

    With LAN using common Ethernet standards (IEEE802.3) such as conventional 100Base-TX or 1000Base-T, multiple computers equipped with communications equipment (network adapter) that supports Ethernet isare connected by star connection to a central switching Hub (also referred to as "layer 2 switching") and communicate freely with each other.

    ...

    With Ethernet multiple computers you can communicate with each other. Here however the computers use a network adapter (also referred to as "LAN Card") which is a special device for connecting to Ethernet, and connect physically to Ethernet.

    ...

    Computers participating in Ethernet must communicate with IDs to prevent them from duplicating each other. Each network adapter has beenis assigned a unique 48-bit ID. This 48-bit ID is referred to as "MAC address". As a rule, the MAC address of the physical network adapter has been assigned, computers would not beis assigned so computers are not duplicated anywhere in the world (in the case of software network adapter such as SoftEther VPN Virtual Network Adapter, a suitable algorithm whereby possibility of MAC address actually being duplicated is extremely low is generated to prevent duplication.

    ...

    The destination MAC address (48 bits) is a field which containing the MAC address that recoversof the recover indicating to which computer the Ethernet frames of the computer sending the frames will be sent. Relaying devices such as a switching Hub within Ethernet read the destination MAC address and relay the Ethernet frames.
