Hetzner's dedicated servers have a limit of 10 firewall rules for their (hardware based) equivalent of AWS Security Groups. And some of those rules already have mandatory entries, so you'll likely only have around 7-8 actually usable. "Just use the firewall in your OS" is a workaround, but doesn't fully cover the same scenario's. That's why AWS has Security Groups after all. This limitation means we have to use smaller sized servers (64/128GB ram), rather than bigger ones which would otherwise be more cost effective. It's a real pita for us, and Hetzner have shown no interest in ever addressing the problem. :( That being said, it's all still a lot cheaper than AWS, as Hetzner doesn't charge for bandwidth with their dedicated servers. :)
