It is certainly a requirement for NAT translating routers (airport base stations and cable/dsl routers, included).This is the world upside down. You are the first person I heard of saying that -P works for them and passive mode doesn't.
Note that I cannot verify this myself. Although I am behind a NAT translating router at home and behind a firewall that blocks most ports at work, I can use either setting, and both of them are working.
Except that the flag passed to curl is '-P -' which is documented as "to make it pick the machine's default".
Now -- I know that I have to turn on PASV in System Preferences to make Finder/Omni/Navigator actually download an ftp URL successfully. And that makes perfect sense.
Now, I present 'curl with verbosity acts I and II'. The first is without '-P -' and the second is with. First fails. Second doesn't. I'm behind a standard LinkSys Cable/DSL router. Same behavior when on other side of NAT'ing airport base station.
