  3. Select Use my Internet connection (VPN).
  4. Enter the VPN server details. Enter the server's domain name or IP address in the Internet address field, then fill in Destination name with something that describes your VPN connection. Then click Done.

Your new VPN connection will be visible under the list of networks. Select the VPN and click Connect. You'll be prompted for your TorGuard username and password. Type them in, click OK, and you'll be connected.

  3. Double-click the newly imported VPN certificate. This brings up a small properties window where you can specify the trust levels. Set IP Security (IPSec) to Always Trust and you'll be prompted for your password again. This setting saves automatically after entering the password.

Now that the certificate is important and trusted, configure the VPN connection with these steps:

  1. Go to System Preferences and choose Network
  2. Click on the small "plus" button on the lower-left of the list of networks.
  3. In the popup that appears, Set Interface to VPN, set the VPN Type to  IKEv2, and give the connection a name.

Finally, click on Connect to connect to the VPN. You should now be connected to the VPN.

Connecting from Ubuntu

To connect from an Ubuntu machine, you can set up and manage StrongSwan as a service or use a one-off command every time you wish to connect. Instructions are provided for both.

Managing StrongSwan as a Service

  1. Update your local package cache: sudo apt update
  2. Install StrongSwan and the related software sudo apt install strongswan libcharon-extra-plugins
  3. Copy the TorGuard IKEv2 Root CA certificate to the /etc/ipsec.d/cacerts directory: sudo cp /tmp/torguard-ikev2-rootca.pem /etc/ipsec.d/cacerts and CHMOD to 600
  4. Disable StrongSwan so that the VPN doesn't start automatically: sudo systemctl disable --now strongswan
  5. Configure your TorGuard VPN username and password in the /etc/ipsec.secrets file: your_username : EAP "your_password"
  6. Edit the file /etc/ipsec.conf to define your configuration.
/etc/ipsec.conf
config setup

conn ikev2-rw
    rightid=vpn.torguard.org
right=server_domain_or_IP rightsubnet=0.0.0.0/0 rightauth=pubkey leftsourceip=%config leftid=username leftauth=eap-mschapv2 eap_identity=%identity auto=start

To connect to the VPN, type:

  • sudo systemctl start strongswan

To disconnect again, type:

  • sudo systemctl stop strongswan

Using a Simple Client for One-Off Connections

  1. Update your local package cache: sudo apt update
  2. Install charon-cmd and related software sudo apt install charon-cmd libcharon-extra-plugins
  3. Move to the directory where you copied the CA certificate: cd <^>/path/to/torguard-ikev2.pem
  4. Connect to the VPN server with charon-cmd using the server's CA certificate, the VPN server's IP address, and the username you configured: sudo charon-cmd --cert torguard-ikev2.pem --host vpn_domain_or_IP --identity your_username
  5. When prompted, provide the VPN user's password.

You should now be connected to the VPN. To disconnect, press CTRL+C and wait for the connection to close.
