When it fails, it fails immediately -- under a second. When it works,
it pauses after the "230-" line for approximately 2-5 seconds.
I'm able to ftp to ftp.netbsd.org no problem from the NetBSD box
that's the NAT/firewall for the network where I'm installing the
system. It's just from *behind* the NAT box that ftp to
ftp.netbsd.org only works about every one in 12 tries. That's why I
suspected the NAT system. But as I mentioned in my previous email,
from the network behind the NAT box, I have experienced no trouble
FTPing to other systems on the Internet.
