FQDN resolution failures in Palo Alto

L4 Transporter


We are experiencing FQDN resolution failures in Palo Alto.

The Palo Alto has connection to the internal DNS; however, it does not resolve the FQDNs.




Please could you help us to verify this issue.

the management interface is configured to use a dns proxy object rather than dns server IPs:

how did you configure the DNS proxy object? was it attached to a dataplane interface? are security rules allowing it to get to the dns servers you configured in the object

if not attached to a dataplane interface, are the dns servers reachable from the management interface?
