Authentication
Authentication for devices that wish to join a VPN takes place using a certificate. The imple-
mentation of certificate-based authentication over the TLS protocol uses public/private key
pairs or X.509 certificates The server and user each possess an individual certificate (public/
private). The OpenVPN server only allows connections signed by a known certification
authority.
The following encryption protocols can also be used.
¤ Activate the required protocols:
Static Key (No X509 PKI)
Simple encryption protocol (one client, one server). A static key is generated from the IP
addresses of the server and client.
¤ Enter the IP address of the OpenVPN server in the Remote Tunnel IP field.
¤ Enter the IP address of your phone in the OpenVPN in the Local Tunnel IP field.
Hardening OpenVPN Security (tls-auth)
In this encryption protocol, all data packets are provided with an additional signature
(HMAC signature = Keyed-Hash Message Authentication Code).
TUN For a routed IP tunnel (routing mode). TUN simulates a point-to-point net-
work device and communicates via IP packets.
TAP For an Ethernet IP tunnel (bridge mode). TUN simulates an Ethernet device
and communicates via Ethernet frames.
