DNS, clients get a page not found error instead of the captive portal screen.  Local sites that are
explicitly listed in the DNS forwarder work, but not general public sites, like google.com.

I'd like it so that if they type in, say, google.com, that they are forwarded even though that site
is currently unavailable.

Though I don't have captive portal experience, a short question:
Have you entered your local/internal DNS server in the System/General 
Setup section?
Maybe that helps captive portal to resolve names. Presumed that this 
server does resolve all URLs.
