Thanks for the reply. I actually do not want 2 HTTP connections. I want to do exactly what you are doing but I cannot get the HTTPS connection to work. I really think that the problem is with my port forwarding configuration in the Airport Extreme because everything else (ISY, iLinc) matches. I have ISY, iLinc, and Airport Extreme set to use port 443 but to no avail. For now i have set the iLinc to a DynDNS address that I have linked to HTTP port 80 so I can connect from anywhere but that means that sitting around my house I am going out over the internet first then back to the ISY instead of staying on the local network.
My Airport Extreme port forwarding configuration is:
internal IP 10.0.1.196
Public TCP 80, 443
Private TCP 80,443
