Using dynamic DNS based rules with Dynamic Objects

Back to Gaia

In order to allow FQDN objects, or even dynamic DNS entries, you could leverage Dynamic Objects, despite it has impacts on SecureXL when using templates.

Create a dynamic object as a destination and place it in your rule, then on the command line do the following:

The dynamic object name here is "dynamic_host" and must match the dynamic object created in the SmartDashboard.

# dynamic_objects -n dynamic_host
Operation completed successfully

To populate the dynamic object run the following:

# dig +short cloud.hostname.com google.com|sort -u|awk '{print $1" "$1}'|xargs dynamic_objects -a -o dynamic_host -r
Operation completed successfully

Check the object has been updated (shows both in the logs in tracker as well):

It's recommended to create a cron task to update this periodically.
