Greetings - I hope you are having a nice day (:
Just wanted to post about a tool I created for simulating network-traffic across firewalls.
This can be useful for:
* Troubleshooting problems with complex rulesets
* Troubleshooting issues where you do not control the source
* Analysing problems without access to the firewall (the admin/user only needs to send you the config-backup & network-export)
* Automating regression tests (CI/CD and Infrastructure-as-Code)
* More
Links:
* Documentation (https://ftf.oxl.app/)
* GitHub: O-X-L/firewall-testing-framework (https://github.com/O-X-L/firewall-testing-framework) (and soon Codeberg..)
* PyPI: pip install firewall-test (https://pypi.org/project/firewall-test/)
BTW: It also works for Linux-Netfilter (IPTables/NFTables)
I would be happy to get some feedback - and feel free to contribute to the project :D :+1:
