OpenVPN settings
You can use OpenVPN to set up a virtual private network (VPN) to conduct secure communi-
cation over an encrypted connection. The security protocols are based on the OpenSSL pro-
tocols SSL (Secure Sockets Layer) and TLS (Transport Layer Security). OpenVPN creates a VPN
tunnel in which remote access to devices and resources of the private network is only possi-
ble for authorised devices. Communication between devices in the VPN only takes place
within this tunnel. Additional functions, such as STUN for bypassing NAT, for example, are not
required.
You can configure your Gigaset DE900 IP PRO as an OpenVPN client.
Prerequisite: An OpenVPN network has been set up. You will require the address of the Open-
VPN server and the authentication data (certificate and key).
