Vertech1,
I can confirm that, at least in the case of my specific router, the UPNP ports are reset after connection is lost. I could check this late in the evening yesterday: the ports set automatically by the EX2 where there no more in the router’s table.
So I proceeded as you suggested: REMOVED these ports from the network section in the configuration tab of the EX2 control panel and ADDED these manually using the router web interface.
After that, I rebooted the router to check that the newly, manually added ports were kept after such reset. They were still there! Then I rebooted the EX2.
The cloud is working now again. I’m beginning to believe that EVERY time that this service was disrupted in the past was due to this port removal phenomenon.
So now, and again, I only have to wait for a few days and see if the cloud service survives both time and other adversities, as conneciton failures. I’m convinced this time it will keep working. If, let’s say, next weekend everything is still OK, I’ll report the issue as closed.
By the way: I’d NEVER let my son to deal with the EX2 / router web interfaces, as you suggested! (“Vade retro, Satan!!!”) ;-) He’s able to surf the web and an specialist to find funny videos in Youtube… that’s all. Any other attempt to understand computers is beyond his abilities or, what is whorse, imagination… So I’ll happily assume all the fuss related to manage my network to avoid a technologic tragedy at home.
Just to finish:
The 9-step instructions post you wrote in this thread seems to be the key to successfully activate the EX2 cloud service. However, the latest discoveries (routers resetting UPNP ports) indicate (or seem to) that a slight revision of these could be published in this forum. For instance, it looks like it’s much safer to go for a configuration where the EX2 sets no UPNP ports at all and this responsibility is left to the router by means of a manual addition of the required ports.
I could do this by myself, but it’s my opinion that you deserve the merit for all this work. If you publish a revised version of such instructions, I’ll be really happy to give as much kudos as I can to this new post and I’ll mark it as the solution for the problem, so other people may find it directly instead of going through all the backs and forths explained since this now long story began.
Of course, this is only a suggestion!!!
At ary rate, THANK YOU VERY MUCH FOR YOUR CONTINUOUS SUPPORT. Your instructions helped me very much to understand how the setup worked, and, of course (assuming that the service is stable now) to solve this annoying problem!
Regards,
Pep.
