The Application will try to use the L2tp/ipsec protocol and if not available from your local network (it may be blocked from the firewall), it will try the use the Pptp protocol. Both the protocol are encrypted.
If the connection fails, you should open the router/firewall ports in your local networks to allow the vpn protocol to flow. In our “Faq” page you can find further information about this issue.
In any moment you can subscribe the service to postpone his expiring date.
