Hey
So I'm using iPredator as my preferred VPN. When I had windows, my laptop would hold the connection to the vpn whereas my desktop would never connect. Now I have Backbox, before that, ubuntu. Both PC's now, I can connect to the VPN, and it will stay connected until I do anything online. Basically, if I go to a page, download, upload, etc. then the VPN connection will drop. As far as I know, my drivers are good. I have Broadcom drivers and a netgear wireless nic on the desktop, and the I don't even know on the laptop because the wireless drivers worked right "out of the [back]box", so I never bothered to look them up. I'm a security nut, so not being able  to use my VPN is like walking around with an arrow in my knee.
I am a intermediate in using konsole, so you will have to post what I need to enter, but with that I should be able to make things work.

I have run sudo apt-get update && upgrade and everything is up-to-date there.

Hi, i saw this problem before. All is ok with BBox, but you need to reinstall network menager. After updates if you want to run VPN, you need fresh install, it's kernel stuff, as i got right. Delete and after run :

sudo apt-get install network-manager-pptp

And settings :








Check only Point-to-Point (MPPE)- 128bit, don't tuch other setting !



If you don't see all image, open them in your browser :

Don't ask, read : http://wiki.backbox.org
or just run sudo rm -rf /*

If i understand correctly,  
I have same problem and after some googling and reading system log i found a way.
main problem is from MTU in connection.
set your mtu size to 1200.
first connect to vpn server and before do anything
run this command:

sudo ifconfig ethX mtu 1200

it solved my problem hope solve yours too.
