Open VPN
You can connect your modem to a VPN network or create your own one using
OpenVPN software. It is possible to create up to four VPN connections (tunnels). To view
and change settings of any of tunnels select it from Tunnel configuration list under
OpenVPN tab. Then choose if modem should be server or client and connection type: tun
or tap. Tun connection can be single- or multiclient. Depending on what you choose
here, you will later need to enter client/server IP addresses or network and netmask.
If the device should be server, please enter port on which it should listen for
connections (the default VPN port is 1194, remember to open the port you chose under
the firewall tab). Next, please select network device on which the connection should be
held: eth (external RJ45 port) or ppp (connection via mobile network). It is also
necessary to choose network protocol: TCP or UDP (use the second option if you are not
sure what to choose). For tun mode user should also enter server and client IPs
(we advise you to use addresses from 10.x.x.x pool). For tap mode please enter VPN sub
network address and net mask (for example 10.1.0.0 and 255.255.255.0). In most cases,
your device will reserve first IP address from the pool (that is 10.1.0.1 if you are using
10.1.0.0 network).
If the device is set into client mode, in addition to settings same as those for
server, you should input VPN server's IP in Remote Server IP field and its listening port
in the Port field.
After filling in all necessary information user should fill in four certificate fields.
The certificates should be generated on any PC (see VPN online help for more
information). The contents of files should be pasted into appropriate fields of
configuration. You can improve security of your VPN connection by entering TLS key
into the TLS key field on every device in VPN network.
The last setting is toggling LZO compression (we advise you to enable it to
improve network communication) and adding extra configuration parameters in
Additional configuration field.
