Fellow Kirupians.. send webpage to people that log on

Kirupians,
I need your help.
Location: Hotspot.
Situation: As a user signs on to our wireless network. Without hijacking it and setting there homepage to us. I need the web browser to launch our homepage.

Or if we do, do that. It reverts to there old page when they leave the hotspot.

Cheers!
Your kirupian li0n.

Anyone have any ideas?

anyone?

it’s a routing problem - you need to set it up so that all domain names and IPs route to the adress of the computer you want to be the homepage.

Thanks njs12345 for the reply. Here’s how I figure it.
Correct me if I’m wrong. It’s been a while.
They have to join our “workgroup” or it has to be the default. For them to have access to the dhcp server. Which in turn is connected to the router, and outbound.
So if I have for example:
Router=10.10.95.1
web server=10.10.95.2

If they are running the same ip scheme, say 10.10.95.65 then the web server is a local address. Now How do I make them see a webpage as soon as they recieve an ip from the dhcp server?

Or can I have them connect to a page before we put them on the network? Do you see what I’m saying? Maybe I’m not explaining it well.
If they wander in to our hotspot. I want a page to come up that will have them sign up or sign in. Any idea?

Any more ideas?

Help!
