7.3 Secure Networks Interconnection or Using VPN
Figure 86: Secure networks interconnection – topology of the example
VPN (Virtual Private Network) is a secured (encrypted) and authenticated (verified) con-
nection of two LANs into one, so it performs as one homogenous LAN. LANs are connected
over public untrusted network (Internet), see fig. 86. In Conel routers you can use more ways
(protocols) for this reason:
•
OpenVPN (it is also configuration item in the web interface of the router), see chapter
4.9 or Application Note [5],
•
IPsec (it is also configuration item in the web interface of the router), see chapter 4.10
or Application Note [6].
You can create also non-encrypted tunnels:
GRE
,
PPTP
and
L2TP
with Conel router. In
combination with IPsec you can use GRE or L2TP tunnel to create VPN.
There is an example of OpenVPN tunnel in the fig. 86. These are the prerequisites for this
example: knowledge of the opposite router IP address, knowledge of the opposite network
IP address (not necessary) and knowledge of the pre-shared secret (key). To create the
OpenVPN tunnel it is necessary to configure the
Mobile WAN and OpenVPN items in the
Configuration section.
