I don't have access to any firewalls, but according to Sun's
RMI FAQ at http://java.sun.com/products/javaspaces/faqs/rmifaq.html,

  30. How does RMI work with firewalls?

  When Java RMI reaches a firewall, it goes through three stages to
  try and pass it. It attempts to use a direct socket connection.

  If this fails, RMI tries HTTP tunneling. Finally, RMI tries to
  pass through by using a cgi-bin script.

So (theoretically, at least) if there's a way through the firewall,
it sounds like RMI will find it :-)
