I have (for now) a single firewall with 2 Ethernet ports. One nic is on the outside and is plugged into our premise device and the second nic is connected to the switch directly. The config is very basic, tagged on vlan's 1,2, and 3, and their are no untagged or "native" vlans configured on that port. In Cisco terms it is a trunk port without a native vlan "switchport mode trunk". There are no routers on any of the internal segments. I'm not worried about routing between the segments. And yes, I have rebooted. I think I'm just missing something.
