Mailing Lists

It's hard to stay up to date because technologies and approaches for firewalls and other Internet security mechanisms change so rapidly. You'll find these mailing lists helpful in keeping informed.

The Firewalls mailing list, which is hosted by GNAC, is the primary forum for folks on the Internet who want to discuss the design, construction, operation, maintenance, and philosophy of Internet firewall security systems. Send a message to with "subscribe firewalls" in the body of the message to subscribe to the list.

The Firewalls mailing list is fairly high volume (sometimes as many as 100 messages per day, though usually more like 10 to 20 per day). To accommodate subscribers who don't want their mailboxes flooded with lots of separate messages from Firewalls, a Firewalls-Digest mailing list is also available. Subscribers to Firewalls-Digest receive daily (more frequent on busy days) digests of messages sent to Firewalls, rather than each message individually. Firewalls-Digest subscribers get all the same messages as Firewalls subscribers; that is, Firewalls-Digest is not moderated, just distributed in digest form.

The Firewall Wizards mailing list is a moderated mailing list for firewall developers. To subscribe, send a message to majordomo@nfr.net with "subscribe firewall-wizards" in the body of the message. More information is available at:
