Hyper-V VLAN issues

BeanAnimal

Issue below is seen in both pfSense and OPNsense
I am completely baffled and looking for help.

HOST Hyper-V 2012RS
Quad Port Intel NIC
Port1 - OS shared with HOST for management 10.15.30.x subnet LAN SWITCH
Port2 not shared with HOST OS tied to physical broadband connection
Port3 not shared with HOST OS tied tp physical LAN SWITCH
Port4 not shared with HOST OS tied to secondary broadband - not part of this GUEST setup

VswitchWAN tied to Port2
VswitchLAN tied to Port3

RUCKUS R600 Wireless AP
SSID1 - no VLAN
SSID2 - Access VLAN20

Switches
Dell PowerConnect series ALL PORTS set to TRUNK

PowerShell - VswitchLAN set to trunk 20 with native 0

GUEST OS
pfSense or OPNsense
Add VLAN 20
Set interface parent to HN1 (LAN)
Add DHCP server for VLAN Interface

Everything works as expected. Wireless clients grab a lease from the VLAN subnet

REBOOT firewall and the functionality breaks. I see no traffic in logs or DHCP requests on the VLAN subnet Setting a host to a static IP on the VLAN subnet also does not work, no traffic. I am at a loss.

Removing interfaces, DHCP and adding them back restores functionality and leases are passed out and traffic flows until next reboot where everything breaks again. I am at a complete loss.

Clearly I am doing something wrong with Hyper-V or the physical setup, but not sure what.

FWIW - IHave tried adding additional vNICS to GUEST and configuring them to Access 20 - then adding the interface to pfSense or OPNsense - but I can not get traffic to flow this way.

Looking for some help here - I really need to get this worked out.

Thanks in advance!
