[En-Nut-Discussion] ethernut in two lans

Hello Grayson,

did you set Ethernut's gateway to 192.168.2.1?

Like Michael, I overlooked this additional tiny little problem.

ICMP replies are a bit special in Nut/Net, because they run
in the Ethernet driver receiver thread. If it gets blocked,
then Ethernet receiving is blocked.

Looking into
http://cvs.sourceforge.net/viewcvs.py/ethernut/nut/ChangeLog?view=markup
there had been a fix in arpcache.c. May be this causes the problem.

If you don't have CVS installed, you may copy the code from CVS
directly from
