PPPoE expiration redirect

i have radius manager that when a client have’t pay he give a private ip to block the access 172.x.x.x , that ok

now i want when a user has expired do redirect the user tho 172.x.x.x/expired.html or domain.com/expired.html the same.

how can i do that ?


And it is possible to send a reminder 2 days before expiration ?

Thank you .

Any one?

Redirect can be done but this will not help you with HTTPS Traffic!
There is another solution for this!
