Powerlinc Modem 2413U

Please help, I am new to this. I connected a powerlinc modem 2413U to my computer and I can connect through wifi to the server, but it can not connect
via my iPhone if I am not on the internet via wifi. I get a message saying "Unable to connect to local Indigo Server"

Hi Dom,

To connect remotely we recommend using our GoPrism reflector service. Information, including steps, can be found here. Note that once you have the reflector setup, you'll need to connect via Indigo Touch on local WiFi to Indigo once initially, then Indigo Touch will store the reflector information so that it can connect remotely automatically when you are not on local WiFi.
