v0.1.0

• Block access or offer to fill in a captcha Our bouncer is able to block access or present a captcha (a.k.a. ban wall and captcha wall).
• Customizable wall pages This bouncer allows you to customize the visual aspect of the ban page and the captcha form (these two pages are called "wall"). You can therefore customize the colors of these pages, modify the texts and translations and even add your own CSS stylesheet if necessary.
• Flex mode : For certain specific uses such as online commerce, it is preferable to never block the user and, in the worst case, you should offer to fill out a captcha. We call this feature "flex mode".
• Support IPv4 and IPv6 : Our bouncer supports both IPv4 and IPv6
• Remedy IPs or IP ranges : Decisions from CrowdSec may concern single IPs or ranges of IPs
• Support for unknown remediations Designed to be extensible, CrowdSec allows you to create as many types of remedies as necessary. Our bouncer can handle all these types of remedies, even those that the bouncer does not yet know.
• CDN Whitelisting : When using CDN, the user's IP is hidden behind the CDN. Fortunately the CDN still transmits the IP through a specific header. To avoid IP spoofing through this header, the bouncer can believe this header only if the CDN IP is included in a list filtered by the bouncer user.
• Bypass mode : Allow the user to temporarily disable bouncing to meet specific needs.
• Events logger : To be Production ready, we have implemented a log system. This will also allow you to consult the bouncer usage metrics later. We use the popular library Winston
