Thanks Michel. I'm at my router configuration page. My next question is, of the options listed on the wiki page, I think the best one for me is: "On your router, make ISY's IP lease permanent (DHCP Reservation)," So under "DHCP Lease time" should I choose "Make Lease Permanent", and will this effect other devices connected to my computer (my web cameras for example)?
I've tried most of the other suggestions and I still get Not Able to Connect to Internet from ISY. I think I have the router configured for port forwarding correctly, as I see the address in ISY as 10.0.0.11
