Yes, router etc. was setup correctly, i am sure of it.
I had connection to other devices on the ip-range too, and scanned the whole range just to be certain.
I also connected directly and again scanned the whole range, nothing.
Now i tried your image, however when i click on the stats page it gives me this:
Error getting device list: ERR: socket connect(0) failed. I checked before and thought every board was properly connected.
and
Error getting version for 127.0.0.1:4028 ERR: socket connect(127.0.0.1:4028) failed
This seems to be an error when the pool connection is not yet achieved.
I am now certain that all network settings are correct, as the device can ping any website without problem.
Edit: Its ALIVE! (muahaha) dont really know what i did to make it work though, it seems as though it will only take pool settings when you´re lucky

... atleast with the dragonminer firmware. Got a good 1th though, so thats nice.
