I think the issue here is more simple. He at first had put his
hostname in and got his public ip-address. I guess he has no local dns
and the address was provided by his providers dns, who off cause could
not have any knowledge of his local addresses.


The hostnames are resolving across the network. When I ping the machines
from different devices, they resolve to their only ipv4 address for the
appropriate interfaces and their global ipv6 address for the same
interface. The pings make their way to the right interface and MAC address.

The challenge with Myth is that it's applying it's own firewalling by
listening for specific addresses. My understanding was that the purpose
historically has been differentiating between link-local/loopback vs public
and this can make sense when you want to limit the interfaces that the
program uses, but this is still essentially acting more as a firewall than
anything else. This worked under ipv4 where each interface used one
address, but breaks in the ipv6 worked where each interface can have
multiple addresses.

Another quirk is that while I'm able to tell Myth to listen for calls to
its hostname under the ipv4 address selection, no such option is available
for the ipv6 field. If this were available under the ipv6 field, the
problem should go away because the resolution will get updated each time my
ISP signs me a new prefix. Perhaps I can try manually overriding this in
MySQL, but that test will have to wait until I finish moving and can unpack
all of my belongings again.
