Hi Michele,

Here the server have the two ports with 172.16.0.1 and two clients,
connected into the two others has 172.16.0.3 and 172.16.0.10

It's there a solution for achieve this?

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
