Architecture of SoftEther VPN
Virtualization of Ethernet devices is the key of the SoftEther VPN architecture. SoftEther VPN virtualizes Ethernet devices in order to realize a flexible virtual private network for bothremote-access VPNandsite-to-site VPN. SoftEther VPN implements the Virtual Network Adapter program as a software-emulated traditional Ethernet network adapter. SoftEther VPN implements the Virtual Ethernet Switch program (calledVirtual Hub) as a software-emulated traditional Ethernet switch. SoftEther VPN implements VPN Session as a software-emulated Ethernet cable between the network adapter and the switch.
You can create one or manyVirtual Hubwith SoftEther VPN on your server computer. This server computer will become aVPN server, which accepts VPN connection requests fromVPN clientcomputers.
You can create one or manyVirtual Network Adapterwith SoftEther VPN on your client computer. This client computer will become a VPN client, which establishes a VPN connections to the Virtual Hub on the VPN server.
You can establish VPN sessions, as called 'VPN tunnels', between VPN clients and VPN servers. A VPN session is the virtualized network cable. A VPN session is realized over a TCP/IP connection. The signals through the VPN session is encrypted by SSL. Therefore, you can safely establish a VPN session beyond the Internet. A VPN session is established by SoftEther VPN's"VPN over HTTPS" technology. It means that SoftEther VPN can create a VPN connection beyondany kinds of firewalls and NATs.
The Virtual Hub exchanges all Ethernet packets from each connected VPN session to other connected sessions. The behavior is same to traditional Ethernet switches. The Virtual Hub has a FDB (forwarding database) to optimize the transmission of Ethernet frames.
You can define alocal bridgebetween the Virtual Hub and the existing physical Ethernet segment by using the Local Bridge function. The Local Bridge exchanges packets between the physical Ethernet adapter and the Virtual Hub. You can realize aremote-access VPNfrom home or mobile to the company network by using the Local Bridge function.
You can define acascading connectionbetween two or more remote Virtual Hubs. With cascading, you can integrate two or more remote Ethernet segments to a single Ethernet segment. For example, after you establish cascading connections between the site A, B and C, then any computers in the site A will be able to communicate with the computers in the site B and the site C. This is asite-to-site VPN.
SoftEther VPN can also establish a VPN session over UDP. The UDP-mode of SoftEther VPN supportsNAT traversal. The NAT traversal function allows the VPN server behind existing NATs or firewalls to accept incoming VPN sessions. You need no network administrator's special permission before setting up a VPN server on the company network behind firewalls or NATs. Additionally, SoftEther VPN Server may be placed on the dynamic IP address environment since SoftEther VPN has built-inDynamic DNS (DDNS)function.
SoftEther VPN Server supports additional VPN protocols, includingL2TP/IPsec,OpenVPN,Microsoft SSTP,L2TPv3andEtherIP. These realizes the interoperability withbuilt-in L2TP/IPsec VPN clients on iPhone, iPad, Android, Windows and Mac OS X, and also withCisco's VPN routersand other vendors VPN products.
How to Use SoftEther VPN ?
SoftEther VPN is an essential infrastructure to build-up IT systems on enterprises and small-businesses.
Ad-hoc VPN
Make an ad-hoc VPN consists of the small-number computers with SoftEther VPN. Despite long-distance, it is easy to communicate mutually with any kinds of LAN-oriented protocols. LAN to LAN Bridge
Geologically distributed branches are isolated as networks by default. SoftEther VPN lays virtual Ethernet cables between your all branches. Then all computers of all branches are connected to the single LAN. | Remote Access to LAN
Does employees need to connect to the company LAN from outside or home? Remote Access VPN will realizes virtual network cable from a Client PC to the LAN from anywhere and anytime. |
SoftEther VPN can build-up flexible and dependable virtual network around Clouds. Amazon EC2, Windows Azure and most of other Clouds are supporting SoftEther VPN.
Join a Local PC into Cloud
| Join a Cloud VM into LAN

Your desktop or laptop PC can join into the Cloud VM network. You can make use of Cloud VM as if it is on your own local network easily.
Your Cloud VM can join to your company LAN with SoftEther VPN. Anyone on your company can access to the Cloud VM without any settings.
SoftEther VPN keeps a virtual dedicate Ethernet line from the Cloud to the LAN 24h/365d. You can consider remote Cloud private network as a part of your corporate network.
Are you using Amazon EC2 and Windows Azure, or using two or more remote datacenters of a Cloud service?SoftEther VPN can make a single united network between all Cloud VMs despite differences of physical locations.SoftEther VPN supports several mobile devices including iPhone and Android. Your smartphone is now a part of your on-premise or Cloud network by using SoftEther VPN.
iPhone and Android
| Windows and Mac Laptops
|
iPhone and Android has a built-in VPN client but originally they need Cisco, Juniper or other expensive hardware-based VPNs for remote-access. SoftEther VPN has a same function to Cisco, and supports your iPhone and Android easily.
Your mobile PCs with Windows or Mac can be easily connected to SoftEther VPN anywhere and anytime, despite firewalls or packet filters on Wi-Fi or overseas ISP. Windows RT is also supported.SoftEther VPN is also an ultra-convenient tool for effective system management by IT professionals on enterprises and system integrators.
Remote Management
Building Your Own Cloud
| VPN for Network Testing, Simulation and Debugging
|
Are you having problem with manyservers, clients and printers of your client companies are distributed around the state? SoftEther VPN will help you a network administrator as a handy tool just from your desk. You can reach to any networks by only installing SoftEther VPN.
Do you want to build and provide your own Cloud service which can beat Amazon EC2 or Windows Azure? SoftEther VPN can help you to build an inter-VMs network and remote-bridging network between your Cloud and your customer's on-premise.
SoftEther VPN is not a program only for building remote network. It can be used for network design, test, and simulation by IT professionals. For example, delay, jitter and packet loss generator is implemented on SoftEther VPN. So network designer can test VoIP phones under the bad-condition IP network.SoftEther VPN is also convenient for home users. You can be proud of using enterprise-class VPN for your home-use.
Remote Access
| Comfortable Network Anywhere
|
Do you want to access to your home server or digital appliance from outside? Set up SoftEther VPN Server on your home PC and gain access to your server or HDTV recorder from anywhere even the opposite side of the earth, through the Internet.
Are you a business man and running around the world? Most of Wi-Fi and local ISPs of several countries are discomfort to use because of packet filtering or censorship. So set up your private relay server on your own home PC and use it from fields to gain ease.Does your network administrator hesitates to assign you a global IP address? Or Does your company has a firewall on the border between the private network and the Internet? No problem! SoftEther VPN has a strong function to penetrate troublesome corporate firewalls.
Dynamic DNS and NAT Traversal
| VPN Azure

Unlike legacy IPsec-based VPN, even if your corporate network doesn't have any static global IP address you can set up your stable SoftEther VPN Server on your corporate network.
If the corporate firewall is more restricted and the NAT Traversal of SoftEther VPN doesn't work correctly, use VPN Azure to penetrate such a firewall.IPsec-based VPN protocols which are developed on 1990's are now obsoleted. IPsec-based VPN are not familiar with most of firewalls, NATs or proxies. Unlike IPsec-based VPN, SoftEther VPN is familiar with any kind of firewalls. Additionally SoftEther VPN requires no expensive Cisco or other hardware devices. You can replace your Cisco or OpenVPN to SoftEther VPN today.

Replacements of Cisco or other hardware-based VPNs
| Replacements of OpenVPN
|
Are you having trouble with IPsec-based legacy VPN products? Replace it to SoftEther VPN. SoftEther VPN Protocol is based on HTTPS so almost all kinds of firewalls will permits SoftEther VPN's packets.
Cisco, Juniper or other hardware-based IPsec VPNs are expensive for set-up and management. They are also lack of usability and compatibility with Firewalls. Replace them to SoftEther VPN. Youcan very easily replacebecause SoftEther VPN also has the L2TP/IPsec VPN function which is same to Cisco's.Screenshots
