  One other thing: I tried using --log-level debug --log-ip log--arp
on the ebtables rules, and had several entries on my syslog such as
this:

Dec 23 19:24:47 hyper kernel: ebtables-broute IN=eth0 OUT= MAC source
= 00:21:a0:ce:9d:24 MAC dest = 00:1a:a2:5d:70:8d proto = 0x0800 IP

  I suppose it means that the ebtables rules are working. But why
aren't they seen by the iptables rules?

  Again, I tried using a single cross-cable connected machine and
these rules worked (and got logged just the the above).

  Could this be a kernel bug?

  Cheers,

Felipe Damasio
