IP Tables (iptables) Cheat Sheet

IPTables is the Firewall service that is available in a lot of different Linux Distributions. While modifiying it might seem daunting at first, this Cheat Sheet should be able to show you just how easy it is to use and how quickly you can be on your way mucking around with your firewall.

Resources

The following list is a great set of documentation for iptables. I used them to compile this documentation.

// AUTO GENERATE SIMPLE UNIQUE ID'S FOR NON-EMPTY ROWS
//
// Author: Carlos Perez, clayperez@gmail.com
//
// Purpose: This Google Sheets script fires when any cell is edited and
// inserts a random (reasonably unique) UID of ID_LENGTH length
// into the specified ID_COLUMN. For instance if the first column in the
// sheet specified by SHEETNAME is the column where you would like the
// UID injected, then ID_COLUMN should be 1.
