[gr]   I went there and got scanned. Here was part of their report; the
part I thought was wrong:

PORT	SERVICE		STATUS
80	WEB		CLOSED
113	IDENT		CLOSED
8	ICMP		OPEN

I know next to nothing about this firewall stuff, but I get the feeling
something's rotten in Denmark. Those ports should be blocked, right? If
so, then how can I block them? All my other ports are blocked (stealth),
according to them, but the ones above are not.

I'm using Shorewall, provided with MDK 9.0. I'm also connected via a
D-Link router and I'm wondering why this isn't protecting me. It's
supposed to have a built-in firewall. What gives?
