serial output from SB-Freeduino via Asus RT-N16?

Hi,

I have a SB-Freeduino with a simple temperature sensor. I want to be able to see the output of the serial port via a VPN connection into the router. There is some information on this here. However that example is for communication going to the arduino, not the other way around.

Is it possible to do what i'm after?

thanks
orfeo
