A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : FTP/TLS Friendly Firewalls
Author(s) : P. Ford-Hutchinson
Filename : draft-fordh-ftp-ssl-firewall-07.txt
Pages : 13
Date : 2005-10-21
This document discusses some of the issues with running FTP, secured
with TLS as defined in [FTP-TLS], through firewalls. FTP is known to
be a bit of a problem for firewalls (see [RFC-1579] for a discussion
of normal FTP and firewalls). Some of the problems have been fixed
by adding intelligence into the firewall. With secured FTP, where
the control connection is encrypted, some of these techniques fail.
Whilst this document confines itself to issues of FTP over TLS, the
issues will probably be relevant for most secured FTP protocols that
conform to [RFC-2228]. Some of the discussions will also be relevant
to any protocol that firewalls do clever things with.

Send a message to:

In the body type:
"FILE /internet-drafts/draft-fordh-ftp-ssl-firewall-07.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
