Graeme,

Yes, it depends where you want to look at your computer from. Whilst
"nmap localhost" or "nmap 127.0.0.1" looks from inside your firewall,
"nmap <your hostname>" should look from outside your firewall. As Ted
says, if you want to look from even further outside, say from outside a
DSL router, then you cannot do it from your computer and you need to
either use the website mentioned or a different internet connection
(e.g. get a friend to do it).

When you used the firewall GUI, you did not check under "trusted
devices" the ethernet port going to your modem/router, did you?
