IIRC back in 22.x due to a bug we had to create a Parent interface for vlan WAN connections or turn on Promiscuous mode. I have read this was fixed and no longer necessary. I tried removing the the Parent on one a system and when I do the WAN interface no longer works. It receives a DHCP address from the WAN but I can't ping anything. I tried deleting the Parent then run the interface wizard to redefine the interface to no avail.
What are the proper steps to removed the Parent to get things working?
Promiscuous mode only works on the parent, because that's the interface that passes (and discards) packets first.
The whole parent debate was about VLANs and where their hardware settings apply, but then people also wanted MAC spoofing per VLAN which introduced the promiscuous mode setting to make it possible... but, again, that only makes sense on the parent an must be set explicitly (since it degrades performance too).
I think you are mixing this up a bit.

Franco, thanks for the reply. Since I have a single VLAN adapter (WAN, LAN. GUEST) and do WAN MAC spoofing. Do I still need a Parent for this setup?
