Help needed on Hotspot

Hi,

We have a hotspot for a client of ours. The current setup is that we use Radius to manage the logins. We have a voucher system and a credit card option. With the credit card the client logins in with trial user, get redirected to our credit card pages. This all works fine. The problem is that the client has free internet access for 5min while the trial user account is active. Now my boss has asked that we find a way to restrict the access for the trial user to only access our credit card page.

Does anyone have a idea how we can do this?

Turn off free trial, add link on front page to page with payment and add this page to walled garden.

Thanks for the help.
