To access multiple App Engine videos on a well-known video website, I set up a VPN based on PPTP on linode. This article will first introduce some information about PPTP VPN, next, we will introduce the creation steps.
PPTP VPN
PPTP, short for "Point-to-Point Tunneling Protocol (point-to-point tunnel protocol)"

What is VPN? It is a virtual private network. The function is to establish a private network on a public network for encrypted communication.

1. Your company network is in a LAN and cannot be accessed from outside. One day you are out on vacation an
Application Introduction
For enterprise users, it is necessary to provide a secure tunnel to the headquarters network for business travelers and remote workstations so that the terminal can access internal resources. With PPTP VPN, terminals can access the Internet via broadband, private network, 3G, WLAN and other access modes, use VPN client dialing, establish a safe tunnel with headquarters r

So, today I am going to introduce VPN Ethernet access technology settings skills, I hope this article can teach you more things, for everyone's life bring convenience. Ethernet has become the most widely used network technol
The previous example deploys a remote access VPN and deploys an instance of a site to the site below:
The site to site VPN connection is two networks. Realize the mutual exchange of computers within two networks. By default, a Site-to-site VPN connection is a demand-dial connection and is established only if network traffic must be forwarded over this interface
The 1,ipsec VPN application is more and more extensive, the following configuration instance is to the single headquarters multiple branch organization actual application
According to the configuration of this article, we can achieve the maximum VPN connectivity through the minimum number of VPN tunnels, the network topology is as follows:

I have a lot of friends because the working relationship is often mobile office, so the transfer of information, and the company information in a timely manner or tired to open a company or home computer to see movies and so on application appears very headache. This application means secure network communication over the Internet, sharing resources. and want to achieve this kind of demand, actually already had the best way to--vpn.

In the real world, we often meet the company's branch offices to visit the company's headquarters or outside the business trip to the company intranet, this time need to be in the branch office or external staff and corporate headquarters to build a dedicated network. Traditional network interconnection schemes have the disadvantages of high cost, poor security and not easy to extend network. At this time, a VPN (virtual private network Network) netwo
Welcome to the Windows community forum, and interact with 3 million technical staff. Win8.1 is also available for nearly a month. It brings a lot of improved interfaces and operations, but it also brings a lot of trouble to users, the commonly used VPN setting function always prompts a connection error. The following is a simple example to show you how to set up a VPN connection on the Windows8.1 platform.
I. User Network Structure
1. the user has two fixed IP addresses in the initial status. The public network goes online, and one Telecom is moved one by one.
2. the VPN device has been connected to three public network ports, in which China Telecom is directly connected to the WAN port of the VPN device, and the mobile line is divided into two lines through a switch, connect to the WAN1 and WAN2 ports of
I have been studying CCNP Security Firewall v1.0 recently. Now the research is complete! It is found that Cisco ASA 8.4 has changed a lot. It is more and more like the checkpoint firewall. The global access control list, whether it is NAT or recently, is exactly the same as that of the cp firewall. After the Firewall v1.0 study is completed, the next research goal is VPN v1.0, which mainly introduces VPN on
I. background for security considerations, the management IP addresses of all network devices in the lab are set in the lab Intranet and connected to the campus network through routers. Therefore, to remotely configure devices in the lab, you must first enter the Intranet. The above factors have been taken into account when designing the lab network, so we purchased a router TL-R478 with VPN functionality. The VPN
modified, but it cannot really let it flow out of the machine. If it goes away, it cannot be expected to encapsulate it with SSL. Where can it flow? The loopback device is a good choice. The data flowing from the loopback device actually flows into the loopback device. In user space, you only need to open the loopback device and then read it, note that the data cannot be read through general sockets. After all, the data is not sent to us. We need to use a packet capture method like this, and us
Setting up VPN Client (PPTP) to connect to some VPN Server shocould be a fairly easy task nowadays-at least most of the online articles/tutorials/videos all suggest so. for example, https://www.youtube.com/watch?

It is in fact very simple --- well, at least for Windows
Where can I purchase a VPN account with a non-fixed IP address? If you do not have a non-fixed IP address, you can purchase it in batches as long as there are many VPN addresses. Note: VPN in China is also supported. I mainly want to avoid being blocked during collection. Where can I buy a VPN account with a non-fixed
Background:It should be very easy to build a pptp vpn Server. However, many of my friends have turned to me for help after reading some articles and have taken many detours.Therefore, I think it is necessary to write an article to explain it. After all, my habit of writing articles is to operate and record while writing articles, so you can do it step by step.Related configuration:OS: CentOS 6.4 x86_64 Minimal1.

Its powerful routing policy tool capabilities and its storage and routing performance go beyond any internal gateway protocol of the image model, therefore, it exists as a "bridge" between autonomous systems. before that, there was an EGP protocol, and few people knew it, because it was not widely used, and it is not used by the US military now, but there are not many po
A Brief Analysis of Dynamic Multi-Point VPN using IPSec tunnel for secure data transmission over the Internet is the main solution for communication between Headquarters and branches of the company. Its commercial value will not be mentioned here, and it will take a long time to find a document. The IPSec network topology can be a star structure (hub-and-spoke) or a mesh structure (full mesh ). In practical applications, data traffic is mainly distrib
