Question:
In the ZLD series, if we want to enable the DNS content filter, we must create a security policy to allow DNS queries from the LAN to the device. For uOS, do we still need to add a security policy to allow DNS traffic from the LAN to the device when using a DNS domain scan?
Answer:
When the UTM DNS domain scan is enabled, the firewall automatically adds an implicit security policy to allow DNS queries from the LAN to the device. Therefore, there's no need to add a security policy for DNS query from the LAN to the device.
