Another addendum to add to this story, a quick check of some ftp daemons shows they will convert the response to (at least HELP) into uppercase. The IPFilter ftp proxy will not accept that as a valid response from a PASV. e.g. $ telnet solaris8 ftp 220 solaris8 FTP server (SunOS 5.8) ready. HELP 227 Entering Passive Mode (h1,h2,h3,h4,p1,p2) 502 Unknown command 227 ENTERING PASSIVE MODE (H1,H2,H3,H4,P1,P2). So if I may reiterate what I said earlier, what the firewall does for data going from the ftp server is not isolated in this problem from what the ftp server does to the input.
