Comment (by mhoran):
I added a ULA prefix to OpenWRT to test the above theory. It turns out
that the ULA prefix does not have a a router associated with the link
subnet.
{{{
2604:2000:1280:a089::/64 via fe80::c43d:c7ff:fe9b:46fc dev wlan0 proto ra
metric 10
fd00:db80::/64 dev wlan0 proto ra metric 10
fd00:db80::/48 via fe80::c43d:c7ff:fe9b:46fc dev wlan0 proto ra metric
10
fe80::/64 dev wlan0 proto kernel metric 256
default via fe80::c43d:c7ff:fe9b:46fc dev wlan0 proto static metric 1024
}}}
This is what I would expect, given hosts should communicate directly with
its subnet as discussed above. So, for some reason, odhcpd seems to be
sending a route to the prefix provided by my ISP pointing to itself as the
router. I'm not sure why the ULA prefix would work fine but the ISP
provided prefix would not.
All communication with challenger via the ULA prefix works just fine. I
can ping6 without receiving "Port unreachable" as above, and SSH works on
the first try.
