SerialIP library - network access without shields

Gah ok, sorry, was thinking of the wrong project :blush: Port 1000 is correct.

It still sounds like the connection manager IPs weren't being assigned correctly though, you should see the RX/TX LEDs blink when you ping the Arduino, if the IPs and gateway are set correctly on your PC (the RX LED will blink even if you don't have the firmware installed, because the PC will send the ping message regardless. You just won't get a response/TX blink until you flash something using SerialIP.)
