Poked around more with this when I got home from work and while I have DHCP on the router (101 and higher for the 4th octet), I for whatever reason have a static IP set on the ISY (.5). I'm wondering if I did it so that I could find it from outside the LAN? It's been so long since I've had to change anything on the setup here, I'm not sure why I did it.... The theory is I shouldn't have to set a static IP to access from outside the LAN, right?
