When AnyDNS is disabled only DNS requests towards the Subscriber Network IP are allowed. When AnyDNS is enabled all DNS requests that enter the subscriber network interface will be processed and responded by the HSMX DNS-service.

Note: Even when AnyDNS is enabled subscribers with misconfigured DNS servers can get no service. This happens when a DNS server is configured in the same IP-space as the subscriber network because the client will not forward these requests to the gateway and cannot be intercepted by the HSMX.
