I have compiled a modified version of the IPFIREWALL kernel but I don't know what that buys me, and all I have used bpf for is tcpdump. This machine will end up being the mail exchanger and bastion host for a small LAN, so I really need to figure out how to use reasonable protection methods. Any pointers to documentation specific to FreeBSD is very appreciated. Thank you for your support. Andrew PS. For everybody with lpr problems - get aps-491 now! This should be in the FAQ.
