I am trying to connect a Windows PPTP VPN. I created VPN connection through the Network configuration in the Settings. I configured VPN credentials such as gateway, username and password. Nothing happens when I enable VPN connection as it can be seen from the pic below:

Do I need to install any extra packages in order to connect a Windows PPTP VPN?
p.s. I am able to connect this VPN through Windows.
Edit: Output of tail -f /var/log/syslog | grep pptp

Try to make vpn connection with this script, not with NM.
Maybe on this way all will work.
Create file with some name and put in
nano name_of_script script
#!/bin/bash function routeadd { route add -host xxx.xxx.xxx.xxx dev ppp0 route add -net dev ppp0 } function makepptp { echo pty \"pptp xxx.xxx.xxx.xxx --nolaunchpppd\" >> /etc/ppp/peers/vpn; echo remotename PPTP >> /etc/ppp/peers/vpn; echo require-mppe-128 >> /etc/ppp/peers/vpn; echo file /etc/ppp/options.pptp >> /etc/ppp/peers/vpn; echo ipparam vpn >> /etc/ppp/peers/vpn; pppd call vpn & } if [ -a /etc/ppp/chap-secrets ]; then rm /etc/ppp/chap-secrets echo $1 PPTP $2 '*' >> /etc/ppp/chap-secrets; else echo $1 PPTP $2 '*' >> /etc/ppp/chap-secrets; fi if [ -e /etc/ppp/peers/vpn ]; then rm /etc/ppp/peers/vpn; echo name $1 >> /etc/ppp/peers/vpn; makepptp; sleep 8; routeadd; else echo name $1 >> /etc/ppp/peers/vpn; makepptp; sleep 8; routeadd; fi In script change you host ip and add network or/and host witch you wish to connect via vpn
Usage:
sudo /path_to_script/name_of_script username password note: set execute permision to script
