I am very very new bie in the world of Ubuntu. I have recently installed Ubuntu 11.10 and I am not able to connect to Windows VPN.

When I login to Windows 8 I am able to connect to VPN using default Windows VPN connection.

Any help pointers?

  • We would need to know what type of VPN you are connecting to. (PPTP, L2TP, IPsec, etc).

Reset to default

Thanks for the additional info.

Try going into "Advanced" on the VPN tab and enable "Use Point-to-Point encryption (MPPE)", set security to "All Available (Default)" and tick the boxes for "Allow BSD data compression", "Allow Deflate data compression", and "Use TCP header compression".

How to set up VPN in Ubuntu (when you know the parameters to configure):

Click the network icon in the panel → VPN Connections → Configure VPN.

addvpn1

Go to VPN tab → Add.

addvpn2

Create.

addvpn3

Enter settings, optionally mark Connect automatically, Save.

addvpn4

You can connect via the network icon in the panel.

connectvpn

Ps. If you're trying to connect to a Windows VPN and still not working, try the below method suggested by Jason Rowe:

Try going into "Advanced" on the VPN tab and enable "Use Point-to-Point encryption (MPPE)", set security to "All Available (Default)" and tick the boxes for "Allow BSD data compression", "Allow Deflate data compression", and "Use TCP header compression".

  • I can't seem to figure out what package that icon on the panel is inside of. I can create a VPN connection but not see that.

click "advanced" button, then only select MSCHAP and MSCHAPv2 authentication methods. You'd better select every option in other fields.

    This does not provide a sufficient answer to the question. Try to add more information, and / or examples.

  • This was the case for me - though I had to disable MSCHAP and only have MSCHAPv2 checked in order to connect. GG, Microsoft.
