Part 2 of the IPTables tutorial series.
IPTables has always been some sort of blind spot for me. Now, creating my own firewall rules seems to be something I might even be able to do (although I probably won't). Thank you for the conveniently short and great introduction.
I cannot tell you what a great service you are providing to the Linux community with tutorials like these. Now home Linux users like me can protect my network. Part 1 was such an inspiration to me that I actually bought a book on IPTables. However your tutorial made it a lot easier for me to take the first step into IPtables. It also made the book a lot easier to read.
