ftp-proxy question

I am having problems passing passive ftp traffic via ftp-proxy. Active 
connection work fine. I tried using the -n flag the control connection 
doesn't translate the server address so the client attempts to make the 
control channel connection itself. Unfortunately I cant open up blanket 
access outbound for whatever random port the ftp server chooses. Does 
ftp-proxy only handle active connections???

Here are the rules from pf.conf ...

rdr on $if_int proto tcp from any to any port 21 -> lo0 port 8021
pass in quick log on $if_int proto tcp from any to lo0 port 8021 keep state
pass in quick log on $if_ext proto tcp from any to $if_ext port > 49152 
keep state

And here is my entry in inetd.conf ....

ftp-proxy       stream  tcp     nowait  root    /usr/libexec/ftp-proxy 
ftp-proxy -V -D 3

BTW : I haven't seen a single entry in /var/log/messages even with the 
-D and -V options specified. Did I not specify this correctly or is 
ftp-proxy just broke in the regard?

Thanks in advance,
-Matthew
