I think you have the second rule's port numbers reversed.
Try changing this to:
# Allow FTP connections
${fwcmd} add pass tcp from any to any 21 setup
${fwcmd} add pass tcp from any 20 to any setup
Unless I got the whole FTP thing wrong, when you ftp to some server's
port 21, the server will use *his* port 20 to connect back to a random
port of yours.
