DirectAccess - Various Problems with Configuration

I'm running DA on Windows 2016 on a virtual machine.  Two NICs behind a edge firewall.

First problem..  the DA Dashboard reports this error with the External NIC

Error: Forwarding is not enabled on the external adapter. This might prevent remote client traffic from reaching the internal network

Causes: Either the external network adapter has a domain profile (and the server is not configured with a single network adapter) or forwarding is not enabled on the external network adapter.

Resolution: Enable forward on the external network adapter.

The external NIC is on showing the domain profile.  I searched on line and made a windows firewall to block the external nic from talking to my DNS servers, but that didn't seem to fix the problem.  What to do about that?

Second Problem:  DirectAccess client IPHTTPS tunnel does not get assigned an IP6 address.

Tunnel adapter iphttpsinterface:
