The FreeBSD Handbook available at www.FreeBSD.org has details on building a custom kernel, as well as adding the kernel options for firewalling. Specifically, you're looking to add an option for IPFIREWALL and support for pseudo- device bpf, which is the Berkeley Packet Filter. Filtering rules are created with the stock /sbin/ipfw. A good reference on ipfw is found firstly in the man pages, but www.FreeBSDDiary.com has some good, real-world examples of ipfw flexing its muscle. -Charlie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
