Typical Situations
7.3 Secure Networks Interconnection or Using VPN
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 Chapter
). The mobile connection has to be enabled.
OpenVPN configuration
OpenVPN configuration is done with the
OpenVPN
item in the
Con-
figuration
section. Choose one of the two possible tunnels and enable it by checking the
Create
1st OpenVPN tunnel
. You will need to fill in the protocol and the port (according to the settings
on the opposite side of the tunnel or Open VPN server). You may fill in the public IP address
of the opposite side of the tunnel including the remote subnet and mask (not necessary). The
important items are
Local
and
Remote Interface IP Address
where the information regarding
the interfaces of the tunnel’s end must be filled in. In the example shown, the
pre-shared secret
is known, so you would choose this option in the
Authentication Mode
item and insert the secret
(key) into the field. Confirm the configuration clicking the
Apply
button. For detailed configura-
tion see Chapter
or the "OpenVPN Tunnel" application note. You can download the PDF
on the Internet at:

Figure 92: Secure networks interconnection – OpenVPN configuration
The
Network
item in the
Status
section will let you verify the activated network interface tun0
for the tunnel with the IP addresses of the tunnel’s ends set. Successful connection can be
verified in the
System Log
where you should see the message:
Initialization Sequence
Completed
. The networks are now interconnected. This can also be verified by using the
ping
program. (Ping between tunnel’s endpoint IP addresses from one of the routers. The console
is accessible via SSH).
