| The default primary interface choice on FreeBSD and OpenBSD is the first non localhost interface alphabetically. This does not really work when a system has more than one interface of differing types. For example: 33>netstat -i
{{ Name Mtu Network Address Ipkts Ierrs Idrop Opkts Oerrs Coll}}
{{ lo0 16384 <Link#1> lo0 235832 0 0 235832 0 0}}
{{ lo0 - localhost localhost 71739 - - 73701 - -}}
{{ lo0 - fe80::%lo0/64 fe80::1%lo0 0 - - 0 - -}}
{{ lo0 - your-net localhost 162449 - - 162672 - -}}
{{ xn0 1500 <Link#2> 00:16:3e:64:48:1a 165100162 0 0 35921722 0 0}}
{{ xn0 - $IP $HOST 19261337 - - 33901320 - -}}
{{ xn0 - fe80::%xn0/64 fe80::216:3eff:fe 0 - - 2 - -}}
{{ xn0 - $IPv6 $DOMAIN 2341250 - - 2016716 - -}}
{{ tun0 1500 <Link#3> tun0 575848 0 0 505291 0 0}}
{{ tun0 - fe80::%tun0/6 fe80::216:3eff:fe 0 - - 1 - -}}
{{ tun0 - 192.168.3.0/2 $HOST.vpn.$DOMAIN 575848 - - 505288 - -}} Facter will pick tun0 as the primary interface. facterversion => 3.14.0 ... networking => { ... primary => "tun0"
} The logic that is used for picking the primary interface on Solaris works here too, just that the netstat -rn columns are different. on FreeBSD: 34>netstat -rn
