For all of us, VPN is not a strange term, its full English name is “Virtual Private Network”, that is, “Virtual Private Network”. In fact, VPN is defined as establishing a temporary and secure connection through a public network, which is a secure and stable tunnel through a chaotic public network. Using this tunnel, data can be encrypted several times to achieve the purpose of safe use of the Internet.
VPN is an extension of enterprise intranet. It can help remote users, company branches, business partners and suppliers to establish reliable and secure connections with the company’s intranet. It can be used to economically and effectively connect to the secure extranet virtual private network of business partners and users. VPN mainly uses tunnel technology, encryption and decryption technology, key management technology and user and device identity authentication technology.
Many friends may know how to create VPN connections on their computers, but how to set up VPN servers under Windows 7? I’m afraid I don’t know a lot about this problem. I’ve just arranged a simple tutorial here to share with you. Next, go straight to the topic and look at the five steps to set up a VPN server under Windows 7:
1. Open Network and Sharing Center and select “Change adapter settings”
Tip: How to quickly access the “Network and Sharing Center”? Click on the network icon in the lower right corner of the computer, and then click “Enter the Network and Sharing Center”.
2. In the menu bar, click File, and then select New Inbound Connection (which is very important)
Tip: What? Why doesn’t my computer have a menu bar? Don’t worry, this really can be, click the Alt key on the keyboard to see the effect, is it magical to appear…
3. Choose an account that allows VPN to connect to the local machine. You can check it from the list or “add users”
Next, choose the way other users connect to VPN, generally speaking, choose “through the Internet”. Of course, if there are many ways to connect, please choose the right way according to your needs.
4. This step is to set the network parameters. If the other party can use the DHCP server of the local network after connecting, then this setting can be skipped. If there is no DHCP server in the local network, it is necessary to set it up first. The specific steps are as follows:
Select “Internet Protocol Version 4 (TCP/IP)”, click the “Properties” button, select “Specified IP Address” (this is set according to the user’s own IP address, set up an unused IP segment). After setting, press OK, and then click “Allow access” to complete.
Tip: The text narrative really looks very tedious, giving people the feeling of ignorance, but the good thing is that the pictures are very detailed, do not want to see the text directly.
5. The VPN server has been set up here. Other users can connect to your network through VPN using the above account number and your IP address. The qualified students should try it quickly.
Two points about firewalls and intranet users are highlighted:
1. If you have a firewall, please allow ports 1723 and 1701.
2. If you are an intranet user, please map ports 1723 and 1701 on the router. Generally, 1723 is enough.
