One more: now I run a kernel built with IPFIREWALL and IPDIVERT, the system is 3.5-STABLE yet. Can I just add IPFILTER and not touch my configuration (e.g. do not setup ipf and ipnat rules)? Can I switch from natd to ipnat on-the-fly then? Eugene To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
