I just installed OpenWRT 23.05 on my laptop as VM and testing how to use Crowdsec with it.
I noticed that Crowdsec console does not see my firewall bouncer but it is installed and working locally
Metadata such as bouncer get synced every few hours, so since this post is 15 hours old, you should be able to see it via the console now.
However, please note there may be a connection issue as the bouncer does not have any ip address so please ensure the service is running and working fine.
