unknow problem with nat

Hi folks... have this problem....

 put this in the console:



      ebtables -t nat -A NONLOCAL -i eth2 -p ipv4 --ip-dst
10.112.128.0/19 --to-dst 00:06:28:3F:1C:E0 --dnat-target ACCEPT



and i obtain this:



      Unknown argument: '00:06:28:3F:1C:E0', ?, '1'.



i was following this tutorial: http://trinityhome.org/misc/bridge034.html

I try with other chains...

If i try this:

             ebtables -t nat -A POSTROUTING -i eth0 -p ipv4 --ip-proto
6 --ip-dport 25 --to-dst 00:08:54:2E:1C:FD --dnat-target ACCEPT


i´ll get this:

            Chain 'FORWARD' doesn't exist.

Maybe some people have an idea that what is happend to me...

Thanks.
