The following guide outlines the steps necessary to install & configure FrootVPN using IPsec on your Ubuntu 16.04:

1. Install StrongSwan

Open terminal and run this commands one by one:

sudo -s
apt-get update
apt-get -y install strongswan
apt-get -y install strongswan-plugin-eap-mschapv2
apt-get -y install libcharon-extra-plugins
apt-get -y install libstrongswan-extra-plugins

2. The following command will replace default configuration file and write required settings. 

Change the following information and run a command:

'conn frootvpn' - Enter a name for the connection you are adding. IE. FrootVPN

'eap_identity=username' - Enter your FrootVPN user name.

'right=server address' - Enter the PPTP or L2TP server address of the location/server that you wish to connect to from our server list

sudo printf '%s\n\t' 'frootvpn' 'keyexchange=ike' 'dpdaction=clear' 'dpddelay=300s' 'eap_identity=username' 'leftauth=eap-mschapv2' 'left=%defaultroute' 'leftsourceip=%config' '' 'rightauth=pubkey' 'rightsubnet=' 'rightid=%any' 'type=tunnel' 'auto=add' >  /etc/ipsec.conf

After this execution of this command you will have configuration file /etc/ipsec.conf like this:

conn frootvpn

3. Disable the "constraints" plugin

 sudo sed -i 's/load = yes/load = no/g' /etc/strongswan.d/charon/constraints.conf

4. Write your credentials into /etc/IPsec.secrets replacing username and password with your FrootVPN username and password

sudo printf '%s' 'username' ' : EAP ' 'password' >> /etc/ipsec.secrets 

5. StrongSwan needs to verify server certificate. As it searches its certificates store, we can link it to the system's OpenSSL certificate store. To do so, execute the following commands:

sudo rmdir /etc/ipsec.d/cacerts
sudo ln -s /etc/ssl/certs /etc/ipsec.d/cacerts

6. Restart StrongSwan daemon so it reads new settings:

sudo ipsec restart 

7. To start the connection just type:

sudo ipsec up your_connection

To disconnect, type:

sudo ipsec down your_connection

Where your_connection is the name of connection you specified in step 2

You can always check the status of your connection by typing:

sudo ipsec status

Once you are connected you will see the message: "connection 'your_connection' established successfully"
