thank you for your answer Nick, after talking with the HOWTO author,
Peter Breuer, it seems that you can firewall, but only with a third NIC. You
get a bridge with two cards, and you firewall your network with a third one.
In my case bridging was not needed, so I simply implemented a routed
configuration. All is fine now.
Thanks for your help,
David.
