I'm also interested in Ethernet Gateway with RS485 transport. At the moment I have successfully tested this on Arduino UNO with 2 different Ethernet modules, W5100 and ENC28J60. In both cases I'm using hardware serial port on Arduino, not AltSoftSerial. // Enable this if RS485 is connected to a hardware serial port #define MY_RS485_HWSERIAL Serial

@hek Sorry for my Late reply. I had an issue with the max485 (ground problem) and the declaration of the node id (was at the wrong position in the sketch). I think, it would be better, if this is also in the examples in the ms library. It cost me some time to find this solution for the node id. But i wasn't sure, if it was the parent or node id
