ebtables iptables DNAT something missing

["Randy Grimshaw" <rgrimsha@syr.edu>]

I thought I followed the recipe for DNAT on a transparent firewall correctly with the statement below, and sniffing shows that the traffic is redirected. But although the client receives the return responses from the server at the dnat destination - the client basically ignores it. (possibly as unexpected noise). What am I missing?

iptables -t nat -D PREROUTING -p tcp --dport 80 -m physdev --physdev-in eth1 -m mark --mark 9 -j DNAT --to-destination 192.168.12.12:80

Thank you
