The concepts are still valid, the principles remain the same. There seems to be a shift from the use of plugs/proxies to stateful packet filters and NAT but that's implementation details. It's the best book I've seen for hands-on understanding of firewalls. But it's not going to be a direct guide to how to config a certain package like IPFW, IPF, Cisco ACLs, TIS FWTK, etc. That's a good thing -- learn the concepts, the figure out what syntax you need for the package you've chosen. Learning the concepts first also helps you to evaluate which products (or combinations of products) you'd prefer to implement, like FWTK, NAT, IPF/IPFW, etc. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
