Hi Jack,
Great! Glad you were able to get the network settings all correct.
Your observed times via 3G is expected. The SmartLinc's design requires many data exchanges to perform tasks like On/Off and status. As a result the cell delay you are observing is expected.
The "E" indicates that MobiLinc is connecting via the External Settings under My Settings->Lighting Controller. "L" indicates local settings.
The auto-setup is a good suggestion. A small number of router vendors have implemented a way for 3rd party products to configure the router for this kind of port forwarding. We may look at this to see if the market satuartion of these types of routers warrent the developement effort to implement this feature.
