Hello,

I'm running 1.6ZK and would like to setup ipfilter. The config has
pseudo-device   ipfilter                # IP filter (firewall) and NAT

But `ipfstat -i -n` tells
ioctl(ipf:SIOCGETFS): Operation not supported by device

`ipf -Fa -f /etc/ipf.conf` tells
ioctl(SIOCIPFFL): Operation not supported by device
3:ioctl(add/insert rule): Operation not supported by device
4:ioctl(add/insert rule): Operation not supported by device

How can I setup ipfilter?
