gressgraph is a software that allows you to visualize your firewall.
gressgraph produces a graph of your iptables ruleset using Graphviz. You can use the graph to:
· Look for vulnerabilities or redundancies.
· Get a "feel" for a network.
· Showcase your firewall.
Developer comments
I've deliberately kept the program simple. It has no command-line options. To change the look of the output just modify the source (don't worry, it's currently only 190 lines of literate Haskell).
I've also only tested it on my own simple network. I'd appreciate hearing about how it works for you. Feel free to include your iptables output.
See the README file in the download for how to contact me, as well as instructions on how to build the program. See the COPYING file for license information (GPLv3).
What's New in This Release:
· This version may not work for all iptables configurations.
