The windows firewall bouncer interacts with the Windows Firewall to block IPs banned by CrowdSec.
It will create multiple rules in the firewall (one rule will contains 1000 IPs) and will manage their lifecycle.
The rules are created on startup and automatically deleted when the bouncer stops.
The .NET 6 runtime is required for the bouncer to work !
You can download either a MSI (containing only the bouncer) or a setup bundle (containing the bouncer and the .NET 6 runtime) from the github releases: https://github.com/crowdsecurity/cs-windows-firewall-bouncer/releases
You can also install the bouncer with Chocolatey (this will automatically install the .NET runtime):
choco install crowdsec-windows-firewall-bouncer
The configuration is stored in
