Hej, Anders -

You might need to make some changes to this.  It goes in /etc/rc.d or
/usr/local/etc/rc.d (more properly).

in /etc/rc.conf you'll need to set dhclient-alias_enable="YES", and
the other variables too

dhclient-alias_if
dhclient-alias_addr
dhclient-alias_mask

dhclient-alias_start()

        ifconfig $dhclient-alias_if inet $dhclient-alias_addr netmask
$dhclient-alias_mask alias

dhclient-alias_stop()

}
