6.3 Secure Networks Interconnection or Using VPN  
Figure 121: 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. 121. You may  
use several different secure protocols.  
OpenVPN (it is a configuration item in the web interface of the router), see Chapter 4.11  
or Application Note [5],  
IPsec (it is also configuration item in the web interface of the router), see Chapter 4.12  
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 Figure 121. To establish this tunnel you will  
need the opposite router’s IP address, the opposite router’s network IP address (not neces-  
sary) and the pre-shared secret (key). Create the OpenVPN tunnel by configuring the Mobile  
WAN and OpenVPN items in the Configuration section.  
Mobile WAN configuration: The mobile connection can be configured as described in the  
previous situations. (The router connects itself after a SIM card is inserted into SIM1 slot and  
an antenna is attached to the ANT connector.)  
Configuration is accessible via the Mobile WAN item the Configuration section, see Chap-  
ter 4.3.1). The mobile connection has to be enabled.
