I'm looking to control internet access for wireless clients. I would like them to see a customizable splash screen containing a disclaimer and then have to enter a password in order to access the internet. One username and password for everyone would be fine. I DON'T want to have to use WEP or any other type of encryption since I want them to be able to connect and see the splash screen before they have to type in the access code. Is there an affordable firewall that will do this for me?
TIA-
Mike
