given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

puppetfinland/openvpn — version 3.3.1 Jun 26th 2018


A module for managing OpenVPN daemons. The module supports template-based servers and clients, as well as those based on a static configuration file with inlined certificates. The former is recommended, because use of static configuration files does not scale well.

The module can optionally reuse existing Puppet certificates for OpenVPN.

Module usage

A Hiera example where a dynamic server with (hopefully) sane default configuration is setup:

    - openvpn

        vpn_network: ''
        vpn_netmask: ''
        use_puppetcerts: false
        tunif: 'tun10'
        - 'route'
        - 'dhcp-option DNS'
        - 'dhcp-option DOMAIN'

Here we setup a client to connect automatically to the above "office" server, and occasionally to an external VPN service provider using a static configuration file and to a customer VPN using password authentication and a dynamically created configuration file:

    - openvpn

openvpn::enable_service: true

        remote_ip: 'office-vpn-server'
        tunif: 'tun10'
        use_puppetcerts: false
        enable_service: true
        remote_ip: ''
        tunif: 'tun12'
        use_puppetcerts: false
        username: 'contractor'
        password: 'verysecret'
        enable_service: false

        tunif: 'tun11'
        enable_service: false

The $enable_service parameter of the main class enables the OpenVPN system service, except on systemd distros, where the parameter makes no difference. The system service will then launch all individual OpenVPN connections which have $enable_service set to true. In the example right above the "office" connection is started automatically on boot, but the "vpn_provider" connection is not.

If you use an external CA, you need to place the CA cert as well as the client/server certificate and key to the Puppet fileserver. By default the module looks for the certificates in these locations:


Even if you decide to reuse Puppet certificates and keys, you need to generate two additional files per OpenVPN network and place them to the Puppet fileserver:

"puppet:///files/openvpn-${title}-ta.key" (TLS auth key)
"puppet:///files/openvpn-${title}-dh.pem" (Diffie-Helmann parameters)

You can override the "puppet:///files" part using the $files_baseurl parameter, for example if you want to store the files in a module or on a different global fileshare.

To create the TLS auth key do

cd /etc/puppetlabs/code/files
openvpn --genkey --secret openvpn-${title}-ta.key

To create the Diffie-Hellman parameters do

git clone
cd easy-rsa/easyrsa3
./easyrsa init-pki
./easyrsa gen-dh
cp dh.pem /etc/puppetlabs/code/files/openvpn-${title}-dh.pem
