I'm not sure what you mean by a "halted firewall". Do you mean that the kernel uses the "halt" instruction when there is no work to do? Actually, if you have APM or ACPI BIOS (all recent machines do), the kernel will use them to conserve power if the machine has been halted for a while, and if the BIOS has that capability. I like Linux iptables because it's flexible and semi-comprehensible, and it can do (almost) everything I want to, and it uses relatively little CPU per packet. But what you really need is a reply from someone who knows both NetBSD and Linux, and can say what's good about NetBSD firewall code. James F.
