Creating VPN Connection on Linux (Ubuntu) using command line (PPTP Client for windows VPN Server)

Last time we see how to create vpn connection on Ubuntu using GUI. Now we create connection by manually editing required file and by executing commands

To successfully configure PPTP VPN Client we need:-

• /etc/ppp/peers/myvpn (Suppose we have given name to tunnel or connection as myvpn for our identity purpose)
• /etc/ppp/chap-secrets
• Server name or ip address of vpn server.
• User name and password to connect vpn server.
• Most important pptp-linux package

Step to create VPN connection:-

• Install Package 
• Create tunnel file . for Eg. I have creating myvpn as a connection or tunnel name.
• Povide authentication information in chap-secrets file
• Dial connection
• Add route

Install Package:-

# apt-get install pptp-linux

Create tunnel file:-

Open the terminal and Create new file and type following details in tunnel file please replace your tunnel file name, user name and server detail high lighted with Red color.

# vi /etc/ppp/peers/myvpn

remotename myvpn

linkname myvpn

ipparam myvpn

pty "pptp vpn.mycompany.com --nolaunchpppd"

name myvpnuser

usepeerdns

require-mppe

refuse-eap

noauth

file /etc/ppp/options.pptp

Provide Authentication details:-

Please change accordingly syntax is “username” “connation name” “User Password” “*”  in following file.

# vi /etc/ppp/chap-secrets

myvpnuser myvpn User@password *

Dial Connection:-

Now dial connection with following command in terminal

Add default Route:-

(every time you need to add this route after vpn connected or you need to crate script for that)

Now open other tab in terminal or other terminal type following command

# route add default ppp0

Check default route added successfully by typing following command

# route

And make sure that following route are show in result
