I'm not sure I understand what the nature of the problem is. Are you saying that the interface is receiving vlan packets meant for other interfaces, or that the vlan tags are not being stripped. It would help if you can provide more information about your setup. Where (on which interface) are vlans 4 and 5 (from your example above) configured?
