Example with hiera

---
classes:
  - openvpn

openvpn::servers:
  'winterthur':
    country: 'CH'
    province: 'ZH'
    city: 'Winterthur'
    organization: 'example.org'
    email: 'root@example.org'
    server: '10.200.200.0 255.255.255.0'

openvpn::client_defaults:
  server: 'winterthur'

openvpn::clients:
  'client1': {}
  'client2': {}
  'client3': {}

openvpn::client_specific_configs:
  'client1':
    server: 'winterthur'
    ifconfig: '10.200.200.50 10.200.200.51'

openvpn::revokes:
  'client3':
    server: 'winterthur'

Don't forget the sysctl directive net.ipv4.ip_forward!

Encryption Choices

This module provides certain default parameters for the openvpn encryption settings.

These settings have been applied in line with current "best practices" but no guarantee is given for their saftey and they could change in future.

You should double check these settings yourself to make sure they are suitable for your needs and in line with current best practices.

Example for automating client deployment to nodes managed by Puppet

Exporting the configurations for a client in the VPN server manifest:

  openvpn::deploy::export { 'client1':
    server => 'winterthur',
  }

Installation, configuration and starting the OpenVPN client in a configured node manifest:

  openvpn::deploy::client { 'client1':
    server => 'winterthur',
  }

ssl_key_size

The default key size is now set to 2048 bits. This setting also affects the size of the dhparam file.

Why

2048 bits is OK, but both NSA and ANSSI recommend at least a 3072 bits for a future-proof key. As the size of the key will have an impact on speed, I leave the choice to use 2048, 3072 or 4096 bits RSA key. 4096 bits is what's most used and recommened today, but 3072 bits is still good.

Cipher

The default data channel cipher is now set to AES-256-CBC

Why

OpenVPN was setting its default value to BF-CBC. In newer versions of OpenVPN it warns that this is no longer a secure cipher. The OpenVPN documentation recommends using this setting.

tls_cipher

The default tls_cipher option is now set to: TLS-DHE-RSA-WITH-AES-256-GCM-SHA384:TLS-DHE-RSA-WITH-AES-256-CBC-SHA256:TLS-DHE-RSA-WITH-AES-128-GCM-SHA256:TLS-DHE-RSA-WITH-AES-128-CBC-SHA256

Why

Details of these ciphers and their uses can be found in the documentation links above.
