hey!
pf blocks me from ftp'ing out from my workstation (behind my pf box) and i
don't know why.
it only blocks, however, the ftp's i've been downloading a lot from during the
past few days.
ftp'ing out *from* my pf box works just nicely.
some of my users report not being able to ssh in, too.

hey...
are you running ftp-proxy, or is it in inetd.conf?
you could try to change the redirect line to:
rdr pass on $int_if proto tcp from $int_if:network port 21 -> 127.0.0.1
port 8021
I don't have this line:
pass in on $ext_if inet proto tcp from any port 20 to ($ext_if) user
proxy flags S/SA keep state
And it works anyway.
