Unbound Windows Config

[Riemann .]

I'm trying to configure Unbound on Windows 7 to forward all requests from
localhost like this:

requests for *.foo.bar => query 172.16.255.3:153
all other requests => query 172.16.255.2

For the first part, this seems to work:

Set "Local Area Connection" IPv4 primary DNS to 127.0.0.1 and add this to
service.conf:

server:
do-not-query-localhost: no

forward-zone:
name: "foo.bar"
forward-addr: 172.16.255.3 at 153

But I want every other request to go to 172.16.255.2 (for example) and
instead, it just dies. I've tried a second forward-zone with the name "."
following the entry above, but it doesn't seem to work. I've completely
disabled the Windows DNS service, in case it matters.
