So I got an ISY-99i pro maybe about a month ago, and immediately installed TouchSwitch and the networking module for it, as well as upgraded the firmware to ver. 2.7.14. My internet access was working fine for a few weeks, but now it seems like whenever I try to access the ISY externally via IP or DNS, it fails. If I go in, disable internet access and then re-enable it, it works for about 24 hours before failing again. Is this any sort of known issue? Could it have anything at all to do with the java issues and macs (I'm reasonably technical, so I know the answer to that is likely no)? Could it possibly be a router issue? I want to use this to its fullest, and not being able to access it half the time when I'm away is really starting to get annoying. Any ideas?

Hello agent0014,

 

Apologies for the inconvenience. In all likelihood, your router issues a different IP address to your ISY and thus breaks its own UPnP forwarding rules.

 

For the most robust installation, it would be best if:

1. You assign a static IP address for your ISY (or make a DHCP reservation in your router)

2. Do not use File | Enable Internet Access (actually Disable it before doing anything else) and instead create the port forwarding rule manually in your router

 

You fill find more details in here (under Configuring Non UPnP Routers).

 

With kind regards,

Michel
