This is done if the user exceeds certain bandwidth limitations and allows the customer to redirect the user to a billing page or what not. DHCP can be used to do this but there is the lease time delay. I was thinking this could be done easier with my local DNS. That way I don't have to make any changes to DHCP and handle it much faster. I was hoping I could use forward-zones-recurse to forward certain users DNS to the customers DNS when required.

I don't think PowerDNS, even with Lua, can do this for you. Have you considered using IPTables to redirect these specific users to a second PowerDNS (or other software) instance?

Kind regards,
