Alibaba Cloud has developed a software client that complies with the PPTP and SSL protocols. This is applicable to an application environment where only one mobile user needs to establish a VPN with the headquarters. It can communicate with VPN Router gateways, support various network access methods, and support NAT traversal. The software operation is complet
able to access the Internet, in addition, the VPN Server has a valid IP address (Internet IP address) on the Internet ). Then, when the VPN Client is successfully connected to the VPN Server through virtual dialing, the VPN Client becomes part of the LAN of the VPN Server.
is a powerful, highly configurable, ssl-based VPN (Virtual Private Network) Open Source software. It has multiple verification methods and many powerful functions. OpenVPN operates on layer 2nd or layer 3rd of the OSI model and uses SSL/TLS protocol for network transmission. Supports various customer authentication methods, such as certificates, smart cards, and user name and password certificates. In addition, there is a powerful ACL function that l

Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we

With the built-in routing and Remote Access capabilities of Windows Server systems, it's no novelty to set up a VPN server, but by this method, a series of complex and cumbersome settings are required, and it is clear that the erection of "engineering" will make many novice users discouraged! In order to be able to chat between, can let you rookie friends easily set up a VPN server, this article deliberatel

Some applications, such as Microsoft Outlook or MSN, are lost in the process of converting them into web-based interfaces. Port forwarding is required.Technology. Port forwarding is used for applications with

This article compares the IPSec VPN and ssl vpn technologies in detail, so that users from all walks of life can better understand the VPN technology and select the appropriate VPN product.

RSA RC-4 or DES. If inbound security is very important for VPN,The server administrator can specify that the server only receives the PPTP package from the remote connection, but this prevents the server from being used as a public web or FTP access question.However, if multiple servers are available and require the highest security, this is an acceptable solution. However, even if all these security measures are taken, the only special software requ
to complete other installation operations, after the installation is complete, the wizard will ask you if you want to restart the server system. At this time, you can make a positive response and ask the server to restart, in this way, the installation task of the Kerio Winroute Firewall tool is completed.

Because the Kerio Winroute Firewall tool has a built-in VPN Server, the installation task of the Kerio Winroute Firewall tool
In general, VPN users are connected to the VPN server is to enter the password, if so, in some public places when the password is likely to cause leakage of passwords, resulting in unnecessary losses. Password Authentication protocol Although the hardware requirements are not as high as the Challenge Handshake protocol, however, in terms of security, it is still a distance from the challenge handshake agree

We can set them according to the actual situation of the enterprise, note that when setting static IP addresses and other information, do not forget to write the DNS address and default gateway address.

What is VPN?
The full name of VPN is "Virtual Private Network", which is translated as "Virtual Private Network ". VPN is defined as a temporary and secure connection through a public network (usually the internet). It is a secure and stable tunnel through a chaotic public network. Using this tunnel can encrypt data several times to ensure secure Internet use.
This article combines two articles and has personally experienced it. It is very good. We have successfully established a VPN dedicated channel! The whole process is actually very simple. First, repeat the LNMP army brother's method and establish a VPN Server. 1. The full text of Server Installation explains how to create a VPN service on VPS, and how to install
