Add rules allowing dynamic DNS updates

You might need to add a rule that allows the Dynamic DNS updates from your Firewall to the specified DNS server.

In addition to creating a rule for inbound load balancing, you might also need to add a rule allowing the Dynamic DNS updates from your Firewall to the specified DNS server.

The Firewall Template allows this traffic by default. If your policy is based on an unmodified Firewall Template, there is no need to add a rule that allows Dynamic DNS updates.
