Hi List, I have been asked in this thread if I would contribute an article on iptables to the Wiki: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=10240&forum=37 The article would be based on a tutorial I have previously written here: http://forums.pcper.com/showthread.php?t=432469 I'm not sure where the article should best go so leave that to your discretion. If you have any further advice on the type or style of article best suited to the Wiki format, please do not hesitate to offer advice, otherwise I would use my existing tutorial as a starting point for a contribution. I have created an account on the Wiki under the username of NedSlider Please do not hesitate to contact me should you require any further information. Be gentle, I'm a Wiki newbie! Regards, Ned
