Hi Michele,

My proposal has nothing to do with netfilter, but you may have a look 
into "Proxy ARP".

Basically you give each interface the same IP address, put in host 
routes based on interfaces (route add -host 172.16.0.3 dev ethx) and 
enable proxy_arp in /proc/sys/net/ipv4/conf/ethx/proxy_arp. This should 
do the trick.

best regards
Bernhard
