I wrote `interactive' (ticks), and I meant addresses that are used to
connect to ssh, web, etc (interactive processes). All these addresses
are NAT-ed. For these, your setup is working fine. Thank you very

The problem, I still have, is the following: the SMTP is flowing
through, I am not relaying e-mail on this host. It seems to me, I
cannot put together a rule which pass the traffic and add it to the
queue except when I use keep-state flag. In this setup (keep-state),
Luigi wrote it does not work.
