Hello, Since I recompiled my system and kernel (4.3-RELEASE) I can't use ipnat ipf and ipfstat: #ipnat /dev/ipnat: open: Device not configured #ipf -Fa -f /etc/ipf.rules open device: Device not configured ioctl(SIOCIPFFL): Bad file descriptor open device: Device not configured 2:ioctl(add/insert rule): Bad file descriptor 3:ioctl(add/insert rule): Bad file descriptor #ipfstat open: Device not configured I did all things needed as MAKEDEV all (done by mergemaster). There are all options unchanged in my kernel configuration file: options IPFILTER #ipfilter support options IPFILTER_LOG #ipfilter logging options IPFIREWALL options IPFIREWALL_VERBOSE_LIMIT=100 #limit verbosity options IPFIREWALL_DEFAULT_TO_ACCEPT options IPDIVERT I don't understand why there is this problem. Anyone could help me ? Chojin To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
