MoRoS GPRS 2.1 PRO Functions
12.6 VPN
12.6.1 VPN General
A VPN (virtual private network) is used to connect IP end devices or entire networks
with each other, in a safe way. The data is transmitted tamper-proof to a destination
and can not be read by third parties.
You can configure the MoRoS GPRS 2.1 PRO for an OpenVPN, PPTP or IPsec con-
nection.
The exact proceeding for creating a certificate structure and configuring a VPN par-
ticipant is described in a series of configuration guides. These are available from our
website (http://www.insys-icom.de/cg/) or our support team (support@insys-tec.de).
12.6.2 OpenVPN General
You can use the MoRoS GPRS 2.1 PRO as OpenVPN server or OpenVPN client.
Figure 6 shows a sample configuration for an OpenVPN connection. One MoRoS
GPRS 2.1 PRO is configured as OpenVPN server and a second as OpenVPN client
here. Both, client as well as server can be replaced by any OpenVPN-capable de-
vices. In the example, a PPP connection between the two devices exists. Via this
PPP connection, an OpenVPN connection is established.
As soon as a WAN connection has been established, IP connections between both
networks can be established. OpenVPN uses an existing WAN connection to estab-
lish a VPN tunnel. A tunnel consists of an IP connection, which transports all pack-
ets to be tunnelled in its payload. OpenVPN will make a virtual network card avail-
able for sending data traffic.

In the sample configuration, the end points of the OpenVPN connection will have
the IP addresses 10.1.0.1 and 10.1.0.2. The VPN tunnel will be established within an
already existing WAN connection. The OpenVPN clients and servers must also know
