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 ADSL 2.1 PRO for an OpenVPN, PPTP or IPsec
connection.
The exact proceeding for creating a certificate structure and configuring a VPN
participant is described in a series of configuration guides. These are available from
our website (http://www.insys-icom.com/cg/) or our support team (support@insys-
icom.de).
13.3.2
OpenVPN General
You can use the MoRoS ADSL 2.1 PRO as OpenVPN server or OpenVPN client.
Figure 7 shows a sample configuration for an OpenVPN connection. One MoRoS
ADSL 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
devices. 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
establish a VPN tunnel. A tunnel consists of an IP connection, which transports all
packets to be tunnelled in its payload. OpenVPN will make a virtual network card
available for sending data traffic.
