Here's an example from one of my firewalls:

Code:

$ ifconfig vr
vr0: flags=28802<BROADCAST,SIMPLEX,MULTICAST,NOINET6> mtu 1500
    lladdr c0:42:10:27:57:d9
    description: << External >>
    priority: 0
    media: Ethernet autoselect (100baseTX full-duplex)
    status: active
vr1: flags=28b43<UP,BROADCAST,RUNNING,PROMISC,ALLMULTI,SIMPLEX,MULTICAST,NOINET6> mtu 1500
    lladdr 00:0d:b9:2f:99:ad
    description: << Internal >>
    priority: 0
    groups: egress
    media: Ethernet autoselect (100baseTX full-duplex)
    status: active
    inet 10.0.1.253 netmask 0xffffff00 broadcast 10.0.1.255
vr2: flags=28843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,NOINET6> mtu 1500
    lladdr 00:0d:b9:2f:99:ae
    description: << PFSync >>
    priority: 0
    media: Ethernet autoselect (100baseTX full-duplex)
    status: active
    inet 10.0.0.2 netmask 0xffffff00 broadcast 10.0.0.255
$
$ cat /etc/hostname.vr0
description "<< External >>"
-inet6
$

The external NIC on this firewall does not have an address assigned during normal operations. Its state is managed by scripts executed by ifstated(8) that monitors a carp(4) interface on the internal subnet.
