Thanks, this was helpful. I got addresses allocated on client machines,
but they don't seem routable.
I can ping6 back to my router using the IPv6 address in the prefix
delegation from my ISP, but I cannot seem to do the same for the
addresses in my ULA prefix.
I was following this guide:
https://www.kuon.ch/post/2022-03-15-openbsd-dhcp-pd/
I modified my /etc/dhcpcd_up.sh to read
```
route sourceaddr -ifp igc0
```
... where igc0 is my ISP-facing interface. I assigned a static ULA to
the same interface as an alias. Not sure if that's relevant, but it felt
relevant to mention.
On the router, netstat -rn shows a route to my client in the ISP prefix,
but no route in my ULA prefix.
Is there something additional I need to do to enable communication over
addresses in my ULA prefix?
