Broken links in Firewall page

[chris@…]

There a few broken links in the "Setting Up a Network Firewall" page. This includes...

Both links to ibm.com - ​http://www-106.ibm.com/developerworks/security/library/s-fire.html and ​http://www-106.ibm.com/developerworks/security/library/s-fire2.html

The link to ​http://www.linuxgazette.com/issue65/stumpel.html, which now redirects to linuxjournal.com, and I think the link to that issue should be ​http://www.linuxjournal.com/issue/65/, but I don't know which article

The link to ​http://logi.cc/linux/athome-firewall.php3 which apparently is now a home-buying site

The link to ​http://www.linux-firewall-tools.com/linux/ - that page is not found, and an attempt to go to the main site results in a request for a username and password.

The link to ​http://www.robertgraham.com/pubs/firewall-seen.html results in "Server not found"
