I have a strange problem in 2.4.12 that a ping from
my machine 172.25.4.9 to 192.168.12.1 works but a
ping the other way does not.
The ping going out goes to the correct route but
a ping reply from the other machine goes to the
default route.
>From my setup, and a dump of 2 packets that show that MAC dst.
On the echo req it has the correct dst, but on the echo reply
the dst is the default route.
The output is from 2 seperate pings and I cut down on the output.
