i made a mistake.
the subnet i get is 255.255.255.0, u were right.
and it's weird cause i also have it written in many places to try
reproduce that config on m0n0
that's the only mistake.
my question is:
why do mac, pc, linux fedora core 1 get all the details and connect to
while m0n0 refuses to?
this is really turning me nuts
