Enough hosts can be connected to a public network (with public IP addresses) and an internal network (with private IP addresses. When a host is not connected to the public network, it can only be accessed in two ways:
- By connecting to a host connected to both the public network and the internal network.
- By connecting to the VPN (which is running on a host connected to both the public network and the internal network).
The service is created on the host specified by the –host argument:
$ enough --domain example.com service create --host bind-host openvpn
VPN Server configuration¶
The OpenVPN server is configured with variables (see the documentation).
The default subnet used by the internal network and routed by the VPN on the client machine is defined in a configuration file that may be modified in case it conflicts with an already used subnet.
VPN Clients creation¶
The certificates for clients to connect to the VPN will be created from the list in the openvpn_active_clients variable in ~/.enough/example.com/inventory/group_vars/all/openvpn.yml, using this example.
For each name in the openvpn_active_clients list, a .tar.gz file will be created in the ~/.enough/example.com/openvpn/ directory. For instance, for
--- openvpn_active_clients: - loic - glen
After running enough –domain example.com playbook, the files ~/.enough/example.com/openvpn/loic.tar.gz and ~/.enough/example.com/openvpn/glen.tar.gz will be created and will contain the credentials.
On Debian GNU/Linux the .tar.gz can be extracted in a vpn directory and the .conf file it contains imported using the Network => VPN system settings.
VPN Clients retirement¶
When a client should no longer be allowed in the VPN, it must be added in the openvpn_retired_clients list, using this example.
