Hello, look at this:

# /etc/rc.d/ipfilter stop ; /etc/rc.d/ipnat start
Disabling ipfilter.
Installing NAT rules ... ioctl(SIOCGNATS): Operation not supported by device

# /etc/rc.d/ipfilter start ; /etc/rc.d/ipnat start
Enabling ipfilter.
Installing NAT rules ... 0 entries flushed from NAT table

IPnat is not work without ipfilter on my server.
