literal PASV or quote "PASV" won't do the job, because the ftp client has to be able to realize it's in the passive mode and initiate connection.

numnum (numnum)
the PASV command only makes the server jump into passive mode. Solaris and Windows built in command line ftp clients are not capable of doing passive transfer, there is nothing you can do about it. As for Linux, the built in command "passive" can do the trick. In any case, an application level gateway(you can call it a ftp proxy) is the best choice in terms of compatibility and security.
