High-performance network firewalls are faced with the challenge to process network packets at very high rates, and to check each packet against a potentially large number of decision rules. In this talk, we consider stateless packet filtering and look at both software-based and hardware-based approaches to speed up firewalls. First, we show how transformations of a rule set can lead to drastically faster decisions in existing software firewall engines, without changing the semantics of the rule set, and without any modifications to the firewall software. Subsequently, we turn towards FPGA-based packet processing. We show how on-demand auto-generated circuits, tailored to the specific firewall rule set, can be used to process network packets at very high rates.
