Hello guys, i've added a floating ip to eth0 interface, ip addr in fact
shows:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
    link/ether 00:30:48:fc:4c:92 brd ff:ff:ff:ff:ff:ff
    inet 188.165.x.x/24 brd 188.165.225.255 scope global eth0
    inet 94.23.x,x/32 scope global eth0
    inet6 fe80::230:48ff:fefc:4c92/64 scope link
       valid_lft forever preferred_lft forever

but it seems that kernel is dropping the packets, in fact when i run
tcpdump with -p option (non-promiscous mode) i can see packets
to 188.165.x.x ip, but not to 94.23.x.x which i can see if i run tcpdump in
promiscous mode. That way packets doesn't goes trough iptables and dnat
isn't working properly.

Please give me some pointers, i'm days behind this and can't get it solved.

Thanks in advance
Best Regards
