In any case i need to have a reproducible problem to investigate it, so your firewall config would help. Also, i wonder, why do you have both ipfw and ipfilter ? You should only use one or the other, not both (of course the system should not crash!) > workaround for F00F bug > Sep 18 16:10:25 area51 /kernel: IP packet filtering initialized, divert > enabled, rule-based forwarding enabled, default to accept, $ > Sep 18 16:10:25 area51 /kernel: DUMMYNET initialized (990504) > Sep 18 16:10:25 area51 /kernel: IP Filter: initialized.
