Responses from request from LAN machines are routed.
But requests from the outside are blocked.
Seeing Internet without being seen provides an enormous security advantage. However, this signifies
that you cannot, a priori, set up your own web server at home to control a home automation
installation from the outside. A solution to this problem, advised by numerous home automation
system dealers, consists in providing outside visibility to your home automation server itself, by
adding a routing rule in the NAT configuration of the DSL router. The issue of this solution is that it
exposes the home automation server to external attacks.
The HTTP callback API solves this issue without having to modify the DSL router configuration. The
module control script is located on an external site, and it is the
VirtualHub
which is in charge of
calling it a regular intervals.
The HTTP callback API uses the VirtualHub which initiates the requests.
Configuration
The callback API thus uses the
VirtualHub
as a gateway. All the communications are initiated by the
VirtualHub
. They are thus outgoing communications and therefore perfectly authorized by the DSL
router.
