Thanks, I have been missed that. Now I can ask my question in other words:

I presume, that http://ebtables.sourceforge.net/br_fw_ia/PacketFlow.png is 
correct.

According to this picture, my packets should flow in lowest path.
To be sure it is so, I have made rules to log incoming packet in 3 points:
a)iptables nat table prerouting chain 
b)ebtables filter table forward chain
c)iptables mangle table forward chain 
d)ebtables filter table input chain

I try to connect fron Internet to aaa.aaa.aaa.12

In case of rule:
iptables -t nat -A PREROUTING -d aaa.aaa.aaa.12 -j DNAT --to-dest 
aaa.aaa.aaa.13

I see packet only in point a)

In case of no rule or rule
iptables -t nat -A PREROUTING -d aaa.aaa.aaa.12 -j DNAT --to-dest 
aaa.aaa.aaa.12

I see packet in a), b) and c) points.

I see also packet in a), b) and c) points if I connect from internet to 
aaa.aaa.aaa.13

It's just like DNAT rule drops packet, but it can't be, because DNAT to the 
same address works fine. I know I have missed something important, but what 
could it be?
