next in thread | raw e-mail | index | archive | help
I
had
a
working
minimal
FreeBSD
system
until
I
put
it
behind
a
wireless
router.
Since
then,
my
network
is
not
accessible
anymore
when
I
boot
BSD.
On
the
same
desktop
I
have
a
Gentoo
Linux
system
which
works
just
fine,
even
if
I
didn't
touch
any
of
it's
configuration
files
after
I
installed
the
router.
The
router
is
a
ZyXEL
P-335U
connected
to
a
cable
modem.
The
desktop
is
plugged
into
a
LAN
port.
A
laptop
connected
by
wireless
has
no
problems.
The
router
gets
it's
IP
from
the
ISP
and
acts
as
a
firewall
and
a
DHCP
server
to
my
network:
it
serves
a
pool
of
32
addresses
starting
at
192.168.1.33.
Its
own
address
is
192.168.1.1.
The
IP
Subnet
Mask
is
255.255.255.0.
The
configuration
files
for
FreeBSD
are
shown
below.
The
output
of
ifconfig
and
netstat
are
also
shown
for
BSD
and
Linux.
What
I
don't
understand
is
the
fact
that
having
the
same
router
settings,
Linux
works
while
BSD
doesn't:
I
can't
even
ping
192.168.1.1,
while
the
same
ping
in
Linux
works.
I
read
the
handbook
and
various
other
BSD
information
sources
on
the
web
and
I
could
not
solve
this
issue.
My
question
is:
which
config
files
do
I
have
to
edit
in
FreeBSD
and
what
settings
should
I
use
?
Can
anybody
help
?
Thanks,
