I wasted a lot of time figuring out I needed to create these: crw------- 1 root wheel 44, 0 Aug 10 20:00 /dev/ipl crw------- 1 root wheel 44, 1 Oct 5 15:29 /dev/ipnat This should be mentioned somewhere in the manpages maybe? I just found the sample MAKEDEV :( (I originally figured it out via /sys/arch/i386/i386/conf.c)
