Can't fmirror security.debian.org

[<kynn@panix.com>]

I have no problem ftp'ing to security.debian.org anonymously, but all
my attempts to fmirror a directory there fail with

  $ fmirror -f ~/security.fmirror
  11:38:51 Connecting to security.debian.org...
  11:38:51 Connected.
  11:39:52 Dir listing failed, exiting. (425 Failed to establish connection.)

What am I doing wrong?

Here's my fmirror input file (~/security.fmirror):

username: anonymous
# also tried username: ftp
password: myemail@myhost.com
host: security.debian.org
remotedir: debian-security/dists/stable/updates
localdir: /home/my_home_directory/security
include: p updates/[^/]+/binary-i386
exclude: p binary-
exclude: p debian-security/dists/[^/]+/updates/[^/]+/source

Thanks!
