By default, nmap will try to discover if the host is active before scanning, which (by default) uses the ICMP echo request / reply method. If the host is not discovered, nmap will consider the host not up (and all ports on it filtered). When you specified -P0, you requested nmap to skip the host discovery phase and perform the TCP connect scan (default scan type) on the port specified. Clear as mud, eh? ;-) So, the results you had in all cases are expected and nmap is performing correctly.it is not so simple :)
My apologizes, I gave some bad advise :-( Time to RTFM :-) Jon
