Ansgar,
You can not bullet proof a computer system by using a firewall even if you block all traffic to and from that system. In most configurations firewalls block inbound connection attempts to *internal* systems, while they permit outbound attempts from those systems.

It is my opinion that firewalls are not security devices as much as they are traffic shaping devices. Their job is to control network connections and the flow of traffic, not to ensure that something can't be hacked.

If it was only true....

It is quite true, you're just underestimating the task of maintaining a
firewall.
