I know that some of you from the list have asked me in the past for a copy of my CentOS based Linux Firewall document. There are also those that have no clue what I am talking about. This is for the former group... There is a new version of my document out. It's changed quite a bit since the last person asked me for it. Some of the changes are: * Updated the scripts in the Useful Shell Scripts section. * Changed the document format to reflect more of a professional document. * Added High Availability. * Many other small items. There is a complete changelog "built in" in the document, so you can compare it to the version that you already have to see what's changed. It's still a PDF, so you don't have to worry about having Word or OpenOffice to view it. Just as before, e-mail me at fwdoc at mybellybutton.com to request a copy of the latest version. Thanks.
