Whonix/Qubes - Windows Networking Help (will even pay)

I have spent days trying to figure this out and I am calling for help.
I need to set up windows 10 going through whonix (in qubes)

I can get windows 10 to work through a normal conneciton eg. sys-firewall

Once I change to sys-whonix it falls apart

I followed instructions to change the windows IP to:

increment last octet of IP address on additional workstations

IP address
Subnet netmask
Default gateway
Preferred DNS server

not working

Can anybody help - I am even willing to pay for freelance work
