The DNS service is configured to allow traffic on port 53 for all IPv4 interfaces. Note that you cannot modify the port value.

To configure a server, complete the following:

  1. From the Infoblox Portal, click Configure > Networking > DNS, and click Global DNS Configuration. 
  2. On the Global DNS Configuration page, click Server, and complete the following:
    • Query Port: The source port for outbound DNS queries. When you set this port to 0, it will use any available port for outbound DNS queries. The default value is 0.

    • Secondary AXFR query limit: The maximum concurrent number of inbound full zone or AXFR transfers. It indicates the maximum number of DNS messages the primary server can send containing only the changed zone data, or the entire data set. The default value is 0. The minimum value is 0 and the maximum value is 65535. When you set the value to 0, the server uses a NIOS-X Server-dependent default value.

    • Secondary SOA query limit: The maximum number of concurrent queries a secondary name server sends to the primary server to find out if the zone serial numbers have been changed. The default value is 0. The minimum value is 1 and the maximum value is 65535.
  3. Click Save & Close to save.
