Virtual private network(VPN) is defined as the establishment of a temporary and secure connection .which is
a stable tunnel through the public network. You can use this tunnel to encrypt the data that is several times
safer than before. Its core is the use of public networks to create a virtual private network.This connection is a
special communication line for enterprises where is located in different places. By Sunlogin VPN we can
establish a simple virtualnetwork that can help remote users company branches business partners and suppliers.
And secure data transmission.

· The application of VPN
So how to build a VPN by Sunlogin
You can access our website(http://sunlogin.oray.com/). Two steps to set up a VPN: client Setting and control
Install our the client of sunlogin remote control(download address: hhttp://sunlogin.oray.com/zh_CN/download/）,
ensure you have opened the VPN module
VPN will create a virtual local NIC, so after installation there a extra local connection.The ip address of VPN is
allocated by Sunlogin. You can’t modify it.
Client settings: three steps to finish settings
Visit our sunlogin website:http://sunlogin.oray.com/, you can find a VPN network option. at the top. Enter the
page then click [create network] label
Three steps to finish
First of all type in some network information
Second choose a network type. We have Peer network and distribution network. Peer network: each network
host with other hosts, which is the most typical network topology options.Distribution network: each host (branch)
can only be interconnected with the central node host, the host is not allowed between interconnected with each
other, for only need to connectinto the central host server enterprise applications. here we choose Peer network.
Third step: choose a member. Which is one of your computer that login in sunlogin client . And click a computer
that need build a VPN service. At the right side we can see the computers have been added in vpn network.
The different between peer network and distributed network is you need to choose the normal members in the
Choose a core member as servicer
Then choose the normal members as visitor
Three steps to complete the formation of sunflower VPN services. After the building is completed, the system
will automatically assign this to each virtual network inside a virtual computerIP address (beginning with 172).
After the communication between these virtual networks to rely on the virtual IP to complete.
Note that these virtual IP is automatically assigned, the user can not be changed manually.
In the field of traditional VPN, they have combined hardware and software when it is provided to the user. We use
hardware as a gateway , software isavailable to mobile users, generally requires input costs.
Below we look at how to use the sunlogin VPN functionality to achieve remote computer management with 0 cost
Software name: Oray Sunlogin remote control(Phddns produced)
Software Version: 126.96.36.199505
Software Size: 18,343KB
Application platform: win2000 WinXp WIn2003 WinVista Win 2008 Win7 Win8
Download website: http://sunlogin.oray.com/zh_CN/download/
For example we have a company which headquartered in Shanghai and has branches in Tianjin Hangzhou
Guangzhou. In Guangzhou we often have to log on Shanghai’s servers for file downloads,and to visit the
company’s OA system.
First we need to build a VPN called “ShangGuang network”
Of course, The name of the network can be modified. Click Sunlogin VPN services list. Then then choose a
VPN network than you want to change.
Then click "Save Changes" button.
Now we can see two computers that are not belong a same local area network. The virtual ip address are
188.8.131.52 and 184.108.40.206 Let’s check if they are connected with each other using ping method.
Packet loss rate is 0, indicating that the machines can connect from Guangzhou to Shanghai.
Ping from Shanghai to Guangzhou
Packet loss rate is 0, indicating that the machines can connect from Shanghai to Guangzhou.
After build successfully, then we need to start to use in practice.
Now in Shanghai we have a folder called "tools shared" the colleagues in Guangzhou need to download the
file, how to achieve it?
First set the property of "tools shared" is allowed to share , as shown:
After setting shared, then enter the computer in Guangzhou, click on the computer - Start - Run, then enter the
virtual IP address of that computer Shanghai: 220.127.116.11, as shown:
Then enter return, you need to enter the computer’s user and password which is shared folder, as shown:
After type in the user name and password. Then enter the directory of shared folder
Double click the “tools shared” then you can enter the folder, as shown:
After entering you can view or download the necessary files.
Access the Web service in remote computer
Now we have installed the Oa service in the computer in Shanghai, as shown:
Now we hope to be able to access the Oa service from Guangzhou , because they are already on the same LAN,
and we can see that port 80 is also accessible and its model is B / S structure
So we can use the virtual machine's IP: 18.104.22.168 to visit here we can enter the address to 22.214.171.124 to
access it in Guangzhou, as shown:
We can see, through the formation of Sunlogin VPN service. We can access the WEB service in different areas
by VPN. The same as website FTP service
financial software ERP systems and housekeeper software.
