[Fiware-robotics] Robotics in FIWARE-LAB: public IP addresses

[Álvaro Arranz]

Hi Gianmario,

the Wirecloud instance on FIWARE Lab is hosted by Red.es, so it cannot use,
directly, the internal IPs provided in FIWARE Lab. However, we can deploy a
VPN service if required, what region of FIWARE Lab are you using?

Cross domain is not a problem for Wirecloud (as it provides a proxy), the
only thing that cannot go through the proxy are the connections to the
websockets created by the Kurento Application, but in that case is very
easy to use the access control headers. Here we can have a problem if we
are going to use the Mashup portal of FIWARE Lab, as it is running over
HTTPS, so the ideal is to also use certificates on the websockets created
by the Kurento Applicaition to avoid some security alerts from the browser.
I think is feasible to ask for certificates and for domain names for the
services we are going to make public for the demo... Anyway, this is not
going to be a serious problem, as the demo can work without those domain
names and certificates (the drawback is that the user will have to accept
connecting with the kurento application server).

Best regards,
Álvaro
