Our client company uses FQDN A and B that Nslookup the same IP, and the firewall has a DNS access policy applied with these FQDN.
Recently, the customer deleted the DNS of B, and if it is normal operation, it should be normal service with FQDN of A, but DNS blocking issue occurred.
In addition, entering FQDN refresh from the CLI does not apply, and only when a commit is made through the GUI, the IP permit policy lookup to domain B of the actual device is applied.
It is confirmed that the policy is applied after committing through the GUI console, but I want to know why it is not applied when you try "fqdn refresh" in the CLI.
I tried to run "request system fqdn refresh force yes", but it was not working.
Best and Regards,
Hi @JoHyeonJae ,
Hard to say what caused it with the information at hand but maybe the FQDN refresh job was failing:
