Nach dem Installieren der Erweiterung, steht ein einfach, konfigurierbarer OpenVPN Server oder Klient zur Verfügung, welcher mit Zertifikaten arbeitet (Server-Multi-Client Betrieb). Die Verbindung auf den OpenVPN Server erfolgt über eine verschlüsselte TLS Verbindung.
+
After the installation of the plugin, an easy configurable OpenVPN Server or Client is available.  The OpenVPN uses certificates used for Servern-Multi-Client setups and an encrypted TLS connection.
  
Der OpenVPN Server kann je nach Einstellung im Bridge oder Tunnel Modus betrieben werden.
+
The OpenVPN Server can be configured for Bridge (tap) or Tunnel (tun) Mode.
  
* Im '''Bridge''' Modus erhalten die verbundenen OpenVPN Klients, eine IP Adresse des internen Netzwerkes und können ohne zusätzliches Routing, alle verfügbaren Dienste erreichen.  
+
* In '''Bridge''' mode a virtual network interface (tap0) is created, which is connected over a network bridge (br0) with the internal network adapter (eth0) of the Dreambox. One or more OpenVPN clients get an IP address of the internal network and can access all available services without additional routing.
* Im '''Tunnel''' Betrieb hat der Klient nur eine Verbindung auf den OpenVPN Server der Dreambox.
+
* In '''Tunnel''' Mode the client only has a connection to the OpenVPN server of the Dreambox.  A virtual IP will be assigned for each client according to the subnet (<code>10.128.0.0/24</code>) which is defined in the server configuration.  The OpenVPN server uses the IP address <code>10.128.0.1</code>. Access to the internal network is not possible by default, but can be enabled by IP forwarding and routing.

 +
==== Requirments for the usage ====
 +
* OpenVPN Server must be configured and startet.
 +
* The OpenVPN Server only supports wired network (no WLAN).
 +
* Portforwarding on the router towards the Dreambox (port 1194/UDP)
 +
* To connect to the Server, the WAN IP must be known, or a [http://dnslookup.me/dynamic-dns/ DDNS] Service should be configured (e.g. [http://www.no-ip.com/ No-IP]).
 +
* Certificates need to be created for each client (OVPN Package).
 +
* OpenVPN needs to be installed on all clients.  Protocols such as IPSec, IKE, PPTP, or L2TP are not supported.

The OpenVPN Server can be configured for Bridge (tap) or Tunnel (tun) Mode.

  • In Bridge mode a virtual network interface (tap0) is created, which is connected over a network bridge (br0) with the internal network adapter (eth0) of the Dreambox. One or more OpenVPN clients get an IP address of the internal network and can access all available services without additional routing.
  • In Tunnel Mode the client only has a connection to the OpenVPN server of the Dreambox. A virtual IP will be assigned for each client according to the subnet (10.128.0.0/24) which is defined in the server configuration. The OpenVPN server uses the IP address 10.128.0.1. Access to the internal network is not possible by default, but can be enabled by IP forwarding and routing.
