In light of the recent questions about firewalls and multicasting I think this may be of interest. I've personally not read it yet.

Title : IP Multicast and Firewalls Author(s) : R. Finlayson Filename : draft-finlayson-mcast-firewall-00.txt Pages : 6 Date : 05-Mar-98 Many organizations use a firewall computer that acts as a security gateway between the public Internet and their private, internal 'intranet'. In this document, we discuss the issues surrounding the traversal of IP multicast traffic across a firewall, and describe possible ways in which a firewall can implement and control this traversal. We also explain why some firewall mechanisms - such as SOCKS - that were designed specifically for unicast traffic, are less appropriate for multicast. Internet-Drafts are available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-finlayson-mcast-firewall-00.txt". A URL for the Internet-Draft is: ftp://ftp.ietf.org/internet-drafts/draft-finlayson-mcast-firewall-00.txt Internet-Drafts directories are located at: Africa: ftp.is.co.za Europe: ftp.nordu.net ftp.nis.garr.it Pacific Rim: munnari.oz.au US East Coast: ds.internic.net US West Coast: ftp.isi.edu Internet-Drafts are also available by mail. Send a message to: mailserv () ietf org. In the body type: "FILE /internet-drafts/draft-finlayson-mcast-firewall-00.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.
