I am fully aware the Windows Firewall only *claims* to do inbound
blocking, but it doesn't even do that.

In the active mode FTP example I gave, on a fully patched system
(including the dial-up patch KB886185) running default rules, Windows
Firewall pops up and *claims* to have blocked the *inbound* data
connection (TCP/20) from the FTP server, but clearly it has not since
the client receives the data.

This misleading behavior occurs regardless of whether the FTP server is
on the local subnet or elsewhere.
