Hi! Continuing the tests, I've found the cause of some problems. 1) In my nova.conf I had the --multi_host=T flag. This was the problem. Removing that the secrules became active. Secrules from Juju samples are working fine now. 2) Pointing the host running juju to use the dnsmasq from nova-

Some considerations ... I don't know if nova remove rules when an instance is terminated. But it seems that some rules are missing. For example, we can se a lot of address in the NAT table, from .4 to .9 ... But, in the FILTER table, we can see rules just to hosts .7 and .18. Chain nova-compute
