Hello Joe,
Thanks for the reply, I'm in the process of learning by doing and
seperating my " home " stuff, XYL's PC etc from my " radio " stuff hence
the reason for not using /24 and choosing /29; the " home " stuff will
be on the next up /29. I did discover that as long as the ipaddresses
were within the same [192.168.1.0] range I could connect from one to
another regardless of the gateway setting , obviously no connection
possible to the outside world from the " wrong " ipaddress.
Regards,
Ian..

Hello Doug,
Thanks for the reply, no wonder I've been getting errors, I'll do as you
suggest, maybe I should RTFM more closely in future <smile>, I had
noticed that the /29 enters the correct netmask.
When I first set up the PI2 I used dhcp and everything was OK.
