Ok, mine is actualy even edgier than that; no transit at all, to paraphrase Steeley Dan. But does anyone have a pointer to a good set of ports to block in each direction through my Shorewall DNAT setup, preferably annotated? On reflection, that's actually only outbound; the necessity to set up inbound DNAT manually makes it a default-deny environment, which is one of the reasons that some people like NAT as a component of an edge firewall.
