Ok... three machines specified below.
the *-prv names refer to the 192.168.100 net, the regular names are
the 192.168.200 net.
m02 is the problem host. It can ping/nfs mount/etc from lorax (de0),
but not from lorax-prv (sis0). d01-prv (fxp0) can ping/nfs mount/etc
from lorax-prv (sis0).
The curious thing is that m02-prv (fxp1) sees the traffic from d01-prv
to lorax-prv, but just can't reply to any of it. When I send traffic
via m02-prv (fxp1) I see the blinky light on the hub indicating
traffic on that port; it just doesn't show up anywhere else under
tcpdump.
