Required INI settings
DNSServerIP=[put a real DNS server here]
The DNS Redirector server is on-site with the HotSpot (necessary to track clients joining and leaving the network) while the IIS server with the hosted pages is located elsewhere. DNS Redirector instances at multiple locations could all point to this central IIS server's IP address. This simplifies administration of the Redirect page (which may incorporate a payment process or Terms & Conditions agreement that needs to be updated in the future) as well as the Blocked page.
