Remote access VPN is a type of VPN that can be built by using SoftEther VPN. You can freely access the computers out in the field or at home that cannot be accessed from Internet such as common company LAN, and can communicate with the application of your choice.
From before remoteRemote access to company LAN has been frequently accomplished byused to frequently be accomplished using PPP protocol by dial-up network such as telephone line or ISDN. Communication speed for these methods is however low, and because it was pay-as-you-go, it was difficult to send or receive a large quantities of data that had takentook an extended amount of time.
...
In order to realize remote access VPN, a SoftEther VPN Server is established in the company LAN and the Virtual Hub and existing physical Ethernet segment created in VPN Server that are connected by bridge connection. Connecting by computer installed with VPN Client from remote to concern the Virtual Hub enables theconcerned Virtual Hub enables remote access to company LAN.
With conventional VPN protocol, even protocols other than TCP/IP that has beenused to be hard to use in many cases will ccan be used via virtual Ethernet. VPN sessions can furthermore be easily established via proxy servers, firewall or NAT that use to be hard for conventional VPN protocol to get through.

Base-to-base VPN, on the other hand it is a VPN connection method whereby multiple bases in physically separated locations that can connect with each other. It is probably the best way for companies or departments where two or more bases already exist or are considering increasing the number of bases.
With base-to-base VPN, the set up computers installed with VPN Server or VPN Bridge at multiple bases and connecting existing physical Ethernet segments of each base and Virtual Hub within the VPN Server or VPN Bridge by local bridge connection. Virtual Hub of another VPN Bridge, etc., is connected by cascade connection to VPN Server of one of several bases. By doing so, physical layer 2 segments of multiple separated bases recognize each other as a single segment. After physical networks among multiple bases are connected to each other, so they can be used as a single segment by SoftEther VPN, they are used just as if they are physically connected by cascade connection using an extremely long network cable. All VPN communication is also encrypted to prevent eavesdropping and tampering.
...
- If the number of computers exceeds several hundred, the volume of communication by protocol using broadcast frames such as ARP and NetBIOS increases and increases the load of VPN connection among bases.
- Because networks that were originally separate become a single large network with the system of connecting layer 2 segments alike, as a rule, it is preferable that computers in the segments belong to the same IP network, but if the total number of computers is too large, it willlarge,it costs a lot to alter the configuration.
