OpenVPN

OpenVPN can tunnel any IP subnetwork or virtual ethernet adapter over a single UDP or TCP port, configure a scalable, load-balanced VPN server farm using one or more machines which can handle thousands of dynamic connections from incoming VPN clients.

Sample pillars

Simple OpenVPN server

openvpn:
  server:
    enabled: true
    device: tun
    ssl:
      authority: Domain_Service_CA
      certificate: server.domain.com
    bind:
      address: 0.0.0.0
      port: 1194
      protocol: tcp

OpenVPN server with private subnet with DHCP and predefined clients

openvpn:
  server:
    ...
    interface:
      topology: subnet
      network: 10.0.8.0
      netmask: 255.255.255.0
      dhcp_pool:
        start: 10.0.8.100
        end: 10.0.8.199
      clients:
      - name: client1.domain.com
        address: 10.0.8.12
      - name: client2.domain.com
        address: 10.0.8.13

openvpn:
  server:
    ...
    topology: subnet
    interface:
      network: 10.0.8.0
      netmask: 255.255.255.0
    dhcp_pool:
      start: 10.0.8.100
      end: 10.0.8.199
    topology: gateway
    device: tun
    mode: p2p
    interface:
      network: 10.0.8.0
      netmask: 255.255.255.0
    endpoint:
      local: 10.8.0.1
      remote: 10.8.0.2
    dhcp_pool:
      start: 10.8.0.4
      end: 10.8.0.255
    routes:
    - network: 10.8.0.1
      netmask: 255.255.255.255
    - network: 10.0.110.0
      netmask: 255.255.255.0
    - network: 10.0.101.0
      netmask: 255.255.255.0

OpenVPN server with custom auth

openvpn:
  server:
    ...
    interface:
      topology: subnet
      network: 10.0.8.0
      netmask: 255.255.255.0
    auth:
      engine: pam/google-authenticator
    ssl:
      authority: Domain_Service_CA
      certificate: server.domain.com

Single OpenVPN client with multiple servers

openvpn:
  client:
    enabled: true
    tunnel:
      tunnel_name:
        autostart: true
        servers:
        - host: 10.0.0.1
          port: 1194
        - host: 10.0.0.2
          port: 1194
        protocol: tcp
        device: tup
        compression: true
        ssl:
          authority: Domain_Service_CA
          certificate: client.domain.com

Multiple OpenVPN clients

openvpn:
  client:
    enabled: true
    tunnel:
      tunnel01:
        autostart: true
        server:
          host: 10.0.0.1
          port: 1194
        protocol: tcp
        device: tup
        compression: true
        ssl:
          engine: salt
          authority: Domain_Service_CA
          certificate: client.domain.com
      tunnel02:
        autostart: true
        server:
          host: 10.0.0.1
          port: 1194
        protocol: tcp
        device: tup
        compression: true
        ssl:
          engine: salt
          authority: Domain_Service_CA
          certificate: client.domain.com

OpenVPN client auth
