Experimental environment:
(1) The company all game servers, only allow an extranet IP to access, need to maintain the server, must first dial to the designated extranet IP.
(2) The company and headquarters communications are to take the VPN channel, the company's internal IP and VPN devices are different network segments, need to be under the VPN device to connect a dual network server
Solution: Through the PPTP protocol under Linux, remote users c
Nowadays, more and more Linux environments are used. For example, if the Headquarters uses Linux, but the branches are scattered and not easy to manage, windows is still used, in general, we connect the branches to the Headquarters through VPN. Generally, VPN includes PPTPVPN, IPSECVPN, and L2TPVPN. PPTP is the easiest and IPSECVPN is the most common. It is supported by various platforms. L2TPVPN is the safest. After many experiments, I finally succee
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 and Mac OS, least 5 minutes for both OSS. however for Ubuntu (not sure for other Linux va

Since the firmware is close to 4 m, you can no longer add it to the firmware. You can delete multiple languages in the firmware and rep

Today, let's talk about how to build a PPTP-VPN in linux, PPTP (Point to Point Tunneling Protocol), that is, Point to Point Tunneling 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 verification protocol (PAP) and Extensible Authentication Protocol (EAP) to enhance secur
VPN (Virtual private network) is an extension of a private network that sends data between a local computer and a remote computer by sharing an Internet or public network connection to simulate point-to-point private connections.
It has good confidentiality and immunity from interference, allowing both sides to be free and secure point-to-point connection.
There are two common VPN services under Linux, one is PPTP and the other is OpenVPN. The forme

Application Introduction
The PPTP VPN PC to site mode provides the terminal with a secure tunnel to the Headquarters network. If you are on a business trip, you can connect to the Internet, use the terminal's own VPN client dial-up connection, and establish a secure tunnel for data transmission.

Build PPTP of VPN Server and vpnpptp
First milestone: Check whether the system supports ppp
[root@m01 ~]# cat /dev/pppcat: /dev/ppp: No such device or address
If the above prompt is displayed, the ppp is enabled and the pptp service can be set up normally. If there are other prompts such as Permission denied, you need to go to the VPS panel to see if there is any enable ppp function switch.
Second milestone
In Vultr VPS, the entire pptp vpn process is manually built using Debian 8 i386 (jessie) as the operating system platform.
Update the server and install the PPTP Service
Apt-get update
Apt-get upgrade
Apt-get install pptpd
Edit/etc/pptpd. conf
Find # localip and # remoteip, delete # And set the ip address
Localip 172.16.31.254
Remoteip 172.16.31.234-238
Edit/etc/sysctl. conf
Remove # net. ipv4.ip _ forwar

Apple's operating system is a Mac OS and is completely different from the familiar operating interface of the win system. So, Mac OS systems want to PPTP/L2TP set naturally and completely different from win systems. Next, let's take a look at the detailed steps of the Mac OS system PPTP/L2TP Setup.
