I like your project, and I’d like to know if crowdsec is able (or with minor changes) to support OpenBSD ? OpenBSD is commonly used as firewall and use pf instead of netfilter/nftables cloud be really great

Hello,
I/We didn’t try building it on (any) BSD, but I guess it might build out of the box ?
However, I’m pretty sure two things aren’t going to go smoothly :
- systemd units : I guess we need to have something more BSD friendly
- pf : cs-firewall-bouncer doesn’t support pf (only iptables/nftables)
