Generate firewall configs for multiple firewall platforms from a single platform-agnostic configuration language through a command line tool and Python API.

Aerleon is a fork of Capirca with the following major additions:

• YAML policy and network definition files and pol2yaml, a converter from Capirca policy DSL to YAML.
• Network definitions with FQDN data.
• New firewall platforms can be added through plugins.
• Typed Python APIs for ACL generation and aclcheck queries.
• A SLSA-compatible verifiable release process.
• A detailed regression test suite.
• Many bug fixes and performance enhancements.

Aerleon requires Python 3.8 or higher.

pip install aerleon

To install via brew:

brew install aerleon

Aerleon provides a command line tool and a Python API that will generate configs for multiple firewall platforms from a single platform-agnostic configuration language. It can generate configs for Cisco, Juniper, Palo Alto Networks and many other firewall vendors.
