Oh, great, thank you, that worked fine, now i've created the floating ip, associated to a vm, in fact when i do
iptables -t nat -L -n i get DNAT all -- 0.0.0.0/0 94.23.x.x to: 192.168.4.34 SNAT all -- 192.168.4.34 0.0.0.0/0 to:94.23.x.x but when i do tcpdump -i eth0 (public interface) i can see incoming packets, but not when i do tcpdump -i br100 where the vm has the 192.168.4.34 ip. So it seems it doesn't route the packets, i've enable ip forward and i got the same result.
