![]() It allows to co-locate a DNS server and a DNS firewall, thus simplify their maintenance. Such configuration is suitable for large organizations that maintain their own DNS servers. In this configuration, a DNS firewall enhances DNS server capabilities by adding an extra layer of filtering before the traffic is received by the DNS server software. DNS traffic is intercepted on a DNS server using a low level packet capture-injection right before reaching the DNS server software. ![]() ![]() DNS clients (consumers) require manual changes to network connection settings to forward DNS traffic to DNS firewalls. The providers of firewall services can manage pools of DNS firewalls in a centralized way and apply the same rules to all consumers. The maintenance of the DNS firewalls is done by service providers that consolidate DNS traffic on dedicated servers before forwarding it to upstream DNS servers. Consumers don't worry about the configuration and maintenance of firewall servers. The main benefit of this configuration is in separation between consumers and providers of the firewall services. DNS firewall is consumed as a service that is delivered by other service providers. This configuration is typically used by mobile devices (mobile DNS clients) due to its simplicity. In this configuration, DNS clients send their requests to a remote DNS firewall instead of DNS servers. This configuration is also often involves DNS proxy working side-by-side with DNS firewall.
