Dear list, A draft of the IPTables HOWTO is now up at: http://wiki.centos.org/HowTos/Network/IPTables At this stage I would very much appreciate any comments/corrections. Also, if anyone would like to build on this to take it further, feel free to do so - I feel I've covered the basics but there is so much more that could be included should someone have the time and inclination. Regards, Ned
