Please note that the DHCP plugin forwards any DNS/WINS attributes it
receives over DHCP to the client using IKE configuration attributes. If
you have both the attr and the dhcp plugin enabled, strongSwan sends the
DNS attributes of each backend.
Does your DHCP server provide the correct DNS server address? If yes,
you may try to disable the attr plugin.

Unfortunately, with that loglevel setting we don't see the messages
encoded/decoded, which is actually very useful information. If you
revert to the default loglevels, we'd see at least how many DNS
attributes strongSwan assigns to the client.
