Hi Raderu,
In order to access your ISY from outside of your network with our Lite version you'll need to port forward through your router to your ISY. We have a high-level guide on how to do this here:
viewtopic.php?f=6&t=123Look under the Manual Port Forward section.
For paid Pro/HD users, we have a cloud service called MobiLinc Connect where your ISY and MobiLinc Pro/HD make a connection in our cloud servers to exchange data in real-time. This allows you to have access to your ISY anywhere with internet access from MobiLinc all without any network configuration changes. MobiLinc Connect is currently free for the first year.
