The only thing is that it could be that you aren't setting the ethernet
hardware address on the four cards all to the same address... The
reason box1 gets through is that it is aliased to the arp address that
maps to one of the cards.. the reason the other boxes don't go through
is that the card isn't seeing the correct mac address to pass it's
filter...
do something like:
for i in 1 2 3; do ifconfig ste$i `ifconfig ste0 | grep ether`; done
and see if that fixes your issue...
