7. CONFIGURATION IN TYP. SITUATIONS
7.3 Secure Networks Interconnection or Using VPN
Figure 91: Secure networks interconnection – sample topology
VPN (Virtual Private Network) is a protocol used to create a secure connection between two
LANs, allowing them to function as a single network. The connection is secured (encrypted)
and authenticated (verified). It is used over public, untrusted networks. (See fig.
91 .) You may
use several different secure protocols.
•
OpenVPN (it is a configuration item in the web interface of the router), see chapter 4.10
or Application Note [5] ,
• IPsec (it is also configuration item in the web interface of the router), see chapter 4.11
or Application Note [6] .
You can also create non-encrypted tunnels: GRE , PPTP and L2TP . You can use GRE or
L2TP tunnel in combination with IPsec to create VPNs.
There is an example of an OpenVPN tunnel in Fig. 91 . To establish this tunnel you will need
the opposite router’s IP address, the opposite router’s network IP address (not necessary) and
the pre-shared secret (key). Create the OpenVPN tunnel by configuring the
Mobile WAN and
OpenVPN items in the Configuration section.
