Do u want all alocal users to be forwarded to fake google site that is
hosted on your LAn or to real google? You cant forward them to real goolgle
if u don't have internet connection.

As to IPs CP will block the traffic if u put iy on the port in another word
if ur web server is on Subnet A and ur user in subnet B and the CP is
between A and B  you would get splash screen with or without DNS, sure if
you don't have wan access and user types in google.com and it cnnnot be
resolvd that what you would get => 404. at this time of the night when my
brain is ofline the only solution that I can think is PROXy or second mono
box that will kill all login comedting like user A connects to mono box B
and ten is requested service is no on subnet B then it goes to subnet C
where is no possible authrntication can occure (say parking page that
instead of login will show something like "welcome to our corp net, we so
cheap company that we didn't buy inet connection :-P "

Subject: [m0n0wall] Using Captive Portal offline?

Does the Captive Portal work without an Internet connection, that is,
without real external DNS?

It looks like the way the CP works now, a URL has to resolve to a real IP
before it redirects to the splash screen.  I'm trying to use the Captive
Portal to forward all users to a local web server in a setup without
Internet access.  But in this particular configuration, with no real
external 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. 

If this is the way the captive portal is supposed to work, is there another
way to redirect all local traffic to a local web server?  The clients won't
ever actually go to the URL they put in, but I'd like it so that if they
type in, say, google.com, that they are forwarded even though that site is
currently unavailable.

Thanks for a great product,
Nate
