Reason: Cannot set DHCP so clients get the DNS Redirector server IP as their sole DNS server, the device insists on handing out the ISP's DNS servers.

1 indicates a possible workaround: Disable DHCP on the router, instead run a DHCP service on the server running DNS Redirector.
2 indicates a possible workaround: Use an alternative firmware such as Tomato or DD-WRT and disable DNS Masquerading.
  Note that using an alternative firmware may reduce performance or even brick the router, proceed at your own risk.
  Our support team cannot assist and will recommend 1 above or tell you to buy a true business-grade firewall.

Mobile device (phone/tablet) limitations...

- If the browser homepage is set to a local file or a site only available on the cellular network, the user will not see your welcome site (implemented via DNS Redirector) until they browse to an Internet site.
- If the cellular carrier (or a corporate policy applied to the device) prefers the cellular network over locally available WiFi, the user may not see your welcome site (implemented via DNS Redirector) unless the device is put in airplane mode (where the cellular radio is turned off).
- For Windows CE devices (Windows Mobile 6 and earlier) after authorization by DNS Redirector users may not be able to browse back to their set home page until the browser is quit/end task (from task manager, or by rebooting the device). This is because simply "closing" an application (or going back to the main screen) doesn't terminate the application, it is still running in the background and the DNS cache is not flushed until the browser is quit.
