[ale] iptables, nonstandard ftp and logging?

[Robert L. Harris]

At this point I'm actually trying from the firewall itself,
 and using ncftp I've set "passive on" and retried.  Even
quicking out of ncftp, checking settings and restarting, I
get the same thing.  An "ls" times out.  I can CD to
my hearts content, but any attempt to get or ls fails.
