I am going to show you different ways to repair your VPN connection if internet doesn’t work.
1_Look if your internet connection works otherwise , connect it.
2_Look at your VPN connection, the number of octets that you receive should be approximately like on the screenshot.
.
3_If it’s not, erase cookies and the cache of internet explorer or firefox . Disconnect and connect again your VPN connection.
4_If the problem persists, download and install Ccleaner, it will clean totally all the bad temp files
Normally, the connection should work.
But, if not , ask me questions i will try to help you. And if you know other ways, tell me, i will publish them.

For Mac users, there could be a problem with MTU settings on a VPN connections.
It is better to set it around 1400
Here’s how to make your new mtu setting persistent. Log in using your administrator account and open a Terminal window. Enter the following:
sudo pico /etc/ppp/ip-up
Type the following two lines into the new file you just created:
#!/bin/sh
/sbin/ifconfig ppp0 mtu 1400
Save the file using Ctrl-O (Write Out) then exit pico using Ctrl-X. Next you must make the file you just created executable. Enter this command:
sudo chmod 755 /etc/ppp/ip-up
