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.

Best Regards
