rc.firewall rule for passive FTP from FTP server side

[Noah]

It appears that FTP clients using FTP are not able to interact passively 
with my FTP server.  I am wondering if there is a rule somebody could 
point me to that works rather well.

${ip} is the IP address fo the server (not the client).

this does not work.

---- snip ----
        #/** Allow setup of FTP PASSIVE **/
        ${fwcmd} add allow tcp from ${ip} to any 1024-65534 keep-state
        ${fwcmd} add allow tcp from ${ip} to any 21 keep-state

cheers,
Noah
