the VPN Server and does not allow direct access to the VPN Server, thus adding a protective layer for the VPN Server. Select a tunnel protocol When a VPN Client accesses a VPN Server, It accesses the server through a virtual tunnel. A tunnel is actually a secure channel through an insecure media (usually the Internet. However, the tunnel is not changed by magic. A tunnel protocol is required. I have previously mentioned that older Windows clients can connect to a VPN network through the PPTP (P

Lvs/nat approach is easiest to implement, and real server uses an internal IP that can save real IP overhead. However, because the execution of NAT requires rewriting the packets flowing through the director, there is a certain delay in speed;When the user's request is very short, and the server's response is very large, it puts a lot of pressure on the director and becomes a new bottleneck, which limits the performance of the whole system.Load Balancing cluster with 3.1.2lvs/tun modeTun refers

. when you use a private network, it feels like a network connected by a VPC. its transmission channel is private and independent, however, the actual data is transmitted through the public network and thus becomes a virtual private network. Key technologies of VPN. security tunnel technology. encryption technology. authentication VPN data transmission protocol pptp. IP-based interconnection network. no Header Compression. no tunneling authentication.

I. Proposal of requirements With the increasing scale of enterprises, setting up branches and offices throughout the province and even throughout the country, enterprise informatization is a powerful tool for enterprises to compete in the market, ERP and OA automation systems are essential to achieve smooth flow of information such as people, finance, and things in enterprises. In the past, the use of leased line networking in China Telecom is very expensive and will bring a heavy burden to ente

This is certainly not the first article on "Quick Guide to building a VPN using Cisco devices, however, we still hope that this guide will become an all-in-one guide for users who use ASA 5505 devices to set up VPN and connect to the Internet. The ASA itself has a setup wizard, but this wizard does not cover all aspects of work required by the user, and some steps are vague, making it difficult for the user to adapt. In fact, our work can be divided into four steps: Set SSL authentication, confi

IP Tunneling), that is, IP Tunneling technology implements Virtual servers. It is basically the same as VS/NAT, but the Real server directly returns data to the client without going through the TOR tor server, which greatly reduces the pressure on the Diretor server. 3. VS/DR (Virtual Server via Direct Routing), that is, using Direct Routing technology to implement Virtual servers. Compared with the previo

Set up pptp server in centos PPTP(Point to Point Tunneling Protocol) Default port: 1723 PPTP is the PPTF protocol. This protocol is a new enhanced security protocol developed on the basis of the PPP protocol. It supports multi-protocol Virtual Private Network (VPN) and can pass the password authentication protocol (PAP) and Extended Authentication Protocol (EAP) to enhance security. This allows remote users to access CEN through an ISP, a direct conne

1. pptp Protocol 1 pptp introduction pptp: Short for PointtopointTunnelingProtocol. Point-to-Point Tunneling is a technology that supports Virtual Private Networks with multiple protocols. through this protocol, remote users can securely access the company's network through the MicrosoftWindowsNT workstation or through the Point-to-Point Protocol installed on windows operating systems, connect to local ISPs through dialing, and connect to the company'

time. After the execution is complete, an encrypted tunnel for server port 5901 and local port 5901 has been created. If the VNC desktop number on the server to be linked is 2, run the following command: vncviewer A. B .C.D: 2. In this way, all data in the opened VNC window is encrypted by SSH. Generally, SSH is used for Windows clients, that is, SSH Secure Shell. The following describes how to configure SSH Secure Shell in Windows to implement Secure Linux Remote Desktop Management with VNC. F

public address; RIP uses a private address to directly respond to the client by adding a router to communicate with the Internet. (3) RS and ctor must be in the same physical network; (4) The request message must be scheduled by ctor, but the response message must not pass through Director; (5) Port ing is not supported; (6) most operating systems can be used for each RS; 3. lvs-tun (ip tunneling): IP tunneling
