I had no route to host w/ ISC DHCP 4.3.0 on OpenBSD 4.9 -- the
patch at end of message got it working. Hint was need for
'%<IF>' using ping6.
I applied the patch on OpenBSD 5.5 w/o checking whether
it's needed -- still works. I don't know about 5.6 (as he
ducks his head).
NOTE: patch applies to ISC tar archive -- I did not start from
ports, so I don't know if it'll apply to patched ports source.
Try it if you like. Good luck.
