I'm fairly new to ASA firewalls so some help is appreciated. Can anyone explain the point of the below config. I thought that normally when using Vlan's there would be no point on configuring a nameif & security level on the main interface? In this case what would configuring an ACL based NAT exemption on the Trunk interface do to traffic on the sub interfaces?
