In our school we must connect to an OpenVPN-server to use the internet. The problem is that many sites are locked.

Is there a possibility to create a second tunnel for connecting to a different OpenVPN-provider and use the second tunnel as system wide proxy?

Answer 1

I see two possibilities here:

1 Using a VM and connection one VPN on the host and one on the guest:

Step 1 Install OpenVPN & a VirtualBox Computer

Text in bold is a terminal command.

First, we need to install the VPN client for Linux users. Windows users can download the > program here and here, and run the installer normally. Mac users can use this GUI for > > OpenVPN for Mac.

Change to the Downloads directory.
Configure the installation.
    ./configure
Compile and install.
    make && sudo make install
Now we need to install VirtualBox. This will allow us to have a virtual operating > > systems running from within our computer. Download VirtualBox: Windows, Mac, Linux.
Install a virtual machine of your choice for Windows or Linux and Mac, then install > OpenVPN to it.

Step 2 Chain the VPNs

Start up your virtual machine, and configure them both.

For Windows users using the default VPN client, use this guide to connect to a VPN. > Linux and Mac users, go here.
Connect to VPN A with your host OS.
Start up your virtual machine of choice, and connect to VPN B with it.
Operate from within your virtual machine, and you will be safe from prying eyes. If > you need to delete the virtual machine, make sure you securely delete it, and your 

information will be safe.

Answer 2

If you want to create your own VPN tunnel, you need, in short:

1. A server that you'll use as openVPN server
2. OpenVPN installed on your machine
3. Administrative rights on your machine
4. change the routing table so everything is routed through the second VPN, except for the IP of the first VPN and the IP of the second VPN.
