AW: [En-Nut-Discussion] Problem with connection to Ethernut

[Oliver Schulz]

Hi Bengan,

Just a short note.

There is one problem with your fix. If the ping comes via a router from WAN,
the ip address of the sending host is saved with the ethernet address of the
router, which doesn't make sense at all.

Cheers,
Oliver.
