Het Dwalt, thanks for the link, followed the instructions ... but it didn't work for me. So Ive used the pinouts listed in the post (plus the ss line from pin d10 identified from the arduino-ethernet-shield-06-schematic.pdf ) with my nano. Then I linked up the ICSP and power lines up and ... hey presto i've got a functioning (if not a little spaghetti like) ethernet gateway.

Thanks very much

Simon
