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