1. Create a new VM, name it, click the ProxyVM radio button, and choose a color and template.
|
||||
|
||||
|
||||
|
||||
|
||||
Note: Do not enable NetworkManager in the ProxyVM, as it can interfere with the scripts' DNS features. If you enabled NetworkManager or used other methods in a previous attempt, do not re-use the old ProxyVM... Create a new one according to this step.
|
||||
|
||||
|
||||
If your choice of TemplateVM doesn't already have the VPN client software, you'll need to install the software in the template before proceeding. Disable any auto-starting service that comes with the software package. For example for OpenVPN.
|
||||
|
||||
|
||||
sudo systemctl disable openvpn.service
|
||||
|
||||
|
||||
You may also wish to install `nano` or another simple text editor for entering the scripts below.
|
||||
|
||||
2. Set up and test the VPN client.
|
||||
|
||||
Make sure the VPN VM and its TemplateVM is not running.
|
||||
|
||||
|
||||
Run a terminal (CLI) in the VPN VM -- this will start the VM. Then create a new `/rw/config/vpn` folder with.
|
||||
|
||||
|
||||
sudo mkdir /rw/config/vpn
|
||||
|
||||
|
||||
Copy your VPN config files to `/rw/config/vpn`. Your VPN config file should be named `openvpn-client.ovpn`) so you can use the scripts below as is without modification. Otherwise you would have to replace the file name. `openvpn-client.ovpn` contents:
|
||||

Files accompanying the main config such as `*.crt` and `*.pem` should also go to `/rw/config/vpn` folder.

Also, the config should route all traffic through your VPN's interface after a connection is created; For OpenVPN the directive for this is `redirect-gateway def1`.

The VPN client may not be able to prompt you for credentials when connecting to the server. Create a file in the `/rw/config/vpn` folder with your credentials and using a directive. For example for OpenVPN, add:
|
||||
|
||||
auth-user-pass pass.txt
|
||||
|
||||
|
||||
Save file `/rw/config/vpn/openvpn-client.ovpn`.
|
||||
|
||||
|
||||
Make sure a `/rw/config/vpn/pass.txt` file actually exists.
|
||||
|
||||
|
||||
sudo nano /rw/config/vpn/pass.txt
|
||||
|
||||
|
||||
Add:
|
||||
|
||||
|
||||
username
|
||||
password
|
||||
|
||||
|
||||
Replace `username` and `password` with your actual username and password.
|
||||
|
||||
|
||||
__Test your client configuration:__ Run the client from a CLI prompt in the 'vpn' folder, preferably as root. For example:
|
||||
|
||||
|
||||
sudo openvpn --cd /rw/config/vpn --config openvpn-client.ovpn
|
||||
|
||||
|
||||
Watch for status messages that indicate whether the connection is successful and test from another VPN VM terminal window with `ping`.
|
||||
|
||||
ping 8.8.8.8
|
||||
|
||||
|
||||
`ping` can be aborted by pressing the two keys `ctrl` + `c` at the same time.
|
||||
|
||||
DNS may be tested at this point by replacing addresses in `/etc/resolv.conf` with ones appropriate for your VPN (although this file will not be used when setup is complete). Diagnose any connection problems using resources such as client documentation and help from your VPN service provider.
|
||||
|
||||
|
||||
Proceed to the next step when you're sure the basic VPN connection is working.
