I've had my ISY 99i for a few years and am just now trying the internet access for the first time. Figured it out pretty easily from this post but having issues.
When I enabled internet access and then went to 'about' I get:
My URL: http://192.168.0.149 (which is my ISY in my home network)
Internet Access: https//192.168.1.64 (which is weird because that doesn't exist in my network, and there is no port)
I've got my ISP address and at home, I turn off wifi on my phone and point to "https://my.isp.address:443" and it works! it takes me to the blue Universal Devices page and I can see and control my devices, scenes, programs etc.
Then after a couple hours I tried it again, and it didn't work. It kept taking me to some Acer website. I went in and realized I left 'enable internet access' enabled, I disabled it and it worked again. Now again this morning I tried it and it immediately took me to this acer website, I went into ISY and 'enabled internet access' and it works again. Very strange.
My System
ISY 99i/IR Pro v3.3.10
UI v4.0.11
Linksys E3000 (ISY reserved IP address and port 443 forwarded)
Netgear 24 port switch that all run through
I do have an Acer Windows Server with videos, photos etc. Maybe it's pointing to that, though it does have it's own reserved IP from the Linksys.
