In previous post, I introduce to you some tips with softwares on Ubuntu. Yesterday I found one stupid issue with network-manager-vpnc package. This is just my fault. However, I hope it can help you if you have the same problem like me.
This is my problem:
After creating a VPN profile, I can remote desktop to the computer in my company BUT I CAN NOT CONNECT TO INTERNET TO BROWSE ANY WEB SITE from my Ubuntu computer at home.
Open your VPN profile, check the checkbox: "Only use VPN connection for these address" and enter the IP ranges below.
After that re-connect VPN connection.
Hope this article can help you in necessary case.
