This got me thinking. It was obvious that the ff02 entry was created by
running "autoconf" on em0. When we initially tried this on 5.6 dhcp6c
failed setting the address on em1 at all if we did not first prime the
interface with "ifconfig em1 inet6 eui64".
It turns out, if we set "autoconf" on both em0 and em1 we can get the
setup to work. This is a bit ugly though since we do not want to accept
router advertisements on the inside interface.
Below are transcripts from trying to get this to work first using
"eui64" (since I assumed this was the most minimalistic way to prime
em1). This still required the manual creation of the /64 route.
Second is the attempt using "autoconf" on the inside interface which
did not require the manual route creation, but the route still pops up
in a bit of a "strange" way. See below for details.

Enabling rtadvd:

At this point ping6 against the windows machine will go out on em0 as we
have seen before:
===
# ping6 XXXX:XXX:XXXX:a01:168:9d7e:b7f:2fcf
PING6(72=40+8+24 bytes) XXXX:XXX:XXXX:a01:d250:99ff:fe51:78e9 -->

Attempting to add the route manually (but using the fe80 address because
I noticed this is how the automatically created routes look):
===
# route add XXXX:XXX:XXXX:a01::/64 -iface fe80::d250:99ff:fe51:78e9%em1
add net XXXX:XXX:XXXX:a01::/64: gateway fe80::d250:99ff:fe51:78e9%em1

It turns out ping6 is still unhappy:
===

However, at this point i noticed our manually created route did not have
the "C" flag set (and this have been true for all prior attempts):

Since the ff02:1:2%em0 route had a "c" flag, it seemed like we might
require the "C" flag on the /64. Re-adding it with the -cloning flag:
===
# route delete XXXX:XXX:XXXX:a01::/64
delete net XXXX:XXX:XXXX:a01::/64
# route add XXXX:XXX:XXXX:a01::/64 -iface fe80::d250:99ff:fe51:78e9%em1 -cloning
add net XXXX:XXX:XXXX:a01::/64: gateway fe80::d250:99ff:fe51:78e9%em1
===
The routing table now looks like this:

And finally the routing table where the /64 has magically been added at
this point (and it is clear it was not added manually because it does
not have the "S" flag) along with some other related route entries:

A to me extra intersting route is this one:
===
XXXX:XXX:XXXX:a01:b91c:34cd:143b:c009 ec:a8:6b:f9:6e:35 UHLc
0 6 - 4 em1
===
This a bit above my IPv6 knowledge, but it looks like a route specific to the
windows host (:c009) has been dynamically created. I guess this is the reason
it is important to create the /64 route with the -cloning flag in the eui64
attempt above.
The dmesg messages for this round:

===
In summary, using the following commands (together with ip6 forwarding enabled)
allows us to have a working setup without any other manual intervention:
===
# ifconfig em0 inet6 autoconf
# ifconfig em1 inet6 autoconf
# dhcp6c -Df -c /etc/dhcp6c.conf em0
# rtadvd em1
===
But like stated initially, we do not really like the idea of enabling autoconf
on em1.
Hope this helps you find out what is going wrong.
