OpenVPN GP4 (en)
|- in Deutsch||- in English|
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.
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.
