It's common problem I think.

I do not have connection after VPN through PPTP is established.

My VPN connection was made according to this tutorial:

please try the following after connecting

Q. I think I have a split tunneling issue. What should I do when a PPTP tunnel comes up on a PC, the PPTP router has a higher metric than the previous default, and I lose connectivity?

A. Run a batch file (batch.bat) to modify the Microsoft routing to resolve this problem. Delete the default and reinstall the default route (you must know the IP address that the PPTP client was assigned, such as 192.168.1.1).

In this example, the network inside the router is 10.13.1.x.
route delete 0.0.0.0
route add 0.0.0.0 mask 0.0.0.0 161.44.17.1 metric 1
route add 10.13.1.0 mask 255.255.255.0 192.168.1.1 metric 1

i found this somewhere you can give it a shot

Hi, we got similar problems (connection with internet was lost when session established) when VPN connection was done via PPTP. Our company uses proxy and to fix the issue we had to add proxy settings additionally to dial-up settings in IE browser in addition to connection settings. Such problem didn't happen with Mozilla browser, only IE

For me it doesn’t matter if I use Firefox of IE, even it doesn’t matter how I connect through cable or GSM modem.

For all cases I must use additional route on local computer.
