VLAN: How do you assign/use the native/untagged VLAN

[jahonix]

@tlum:

…What I'm hearing is that pfSense can't create a default interface dedicated exclusively to untagged traffic...

Where do we lose you when saying:
EM0 is your default interface and handles all untagged traffic.
EM0_VLANxyz rides on top of that, tagged.

You don't need to create it, it's there when you assign a network to a (physical) interface.
