Open a terminal and issue the command sudo ifconfig . Now you should see the virtual network adapter you created earlier. But you do not have an ip address for it.
Issue the command sudo dhclient <virtual_network_adapter_name>
According to the above example : sudo dhclient <vpn_vpn_se>
After few moments you will get an ip address from the VPN Server.
Then issue sudo netstat -rn command to see the routing table. You need to add a static route here.
sudo ip route add <gateway of the ip range of your virtual network adapter>/<subnetmask> via <ip you got for the virtual network adapter>
Except for the last route adding step all of the above steps are one-time work. Now you should be able to connect to the required server through the VPN Client.
