While I was tearing down the firewall the CF-Slot jumped right into my eyes. Every Linux guy might think the same. 🙂
So i debootstraped a CF-card made it bootable and right after the first try, bam, working.
The Hardware got freed from the propritary Linux OS and crappy tools and … Yes the backdoors, bugs and security holes, because you won’t get any free downloadable firmware updates. This is really annoying on Barracuda firewalls. It’s a shitty firewall. Every crappy TP-Link does the same things in production.
