Hi all!

I am trying to use ipfilter on NetBSD 3.0 i386 (I have already successfully
installed and tested it on NetBSD 2.0.2 i386).

# sysctl -w net.inet.ip.forwarding=1
net.inet.ip.forwarding: 0 -> 1

# cat /etc/ipf.conf
pass in  quick on lo0 all
pass out quick on lo0 all

# /etc/rc.d/ipfilter stop
Disabling ipfilter.
open device: Device not configured
SIOCFRENB: Bad file descriptor

# /etc/rc.d/ipfilter start
Enabling ipfilter.
open device: Device not configured
SIOCFRENB: Bad file descriptor
open device: Device not configured
User/kernel version check failed
open device: Device not configured
User/kernel version check failed
2:ioctl(add/insert rule): Bad file descriptor
1:ioctl(add/insert rule): Bad file descriptor

# ipf -V
ipf: IP Filter: v4.1.8 (396)
open device: Device not configured

What's that? Do I need to recompile a kernel?

I thank you in advance,

Sylvain.
