Direct access NLB does not work

I had a problem with HA DA, it was working on one server but not on the other one in NLB.

I checked few things until I discovered that "route print" on the client does not have a route to fd40:....   network - DNS64 subnet for internal network.

Then I discovered that in fact the same route was missing on the second server.

added a route in netsh interface ipv6 add route  IPv6 subnet and made it publish=yes.
