FTP is a very difficult protocol with respect to forwarding and
FireWalls. That's because FTP uses two connections, a command
connection and a data connection. The latter is created on demand.
It is very difficult to forward the data connection.

Workarounds:

  Transfer your data from outside into your LAN (e.g. via "scp")
  and then use a LAN FTP connection to Zope.

  Use WebDAV to directly transfer the content into Zope.

  Use "load_site.py" to import content (and something symmetrically
  for the reverse direction).
