Technical Tip: DNS traffic will not show in the debug if using set source interface and HA-direct enabled

[hazim]

Description	This article describes the DNS traffic will not show in the debug if using a set source interface and HA-direct enabled.
Scope	FortiGate version 6.4, 7.0, and 7.2 above.
Solution	When turning on HA-direct in the HA configuration and using the set source interface for DNS configuration, DNS traffic will not be visible in the debug going out to the configured port: When querying the DNS and debug sniffer will not show any traffic: To solve this issue, it is necessary to remove the set source interface if enabling the HA-Direct configuration in the FortiGate. Then the DNS traffic will be sent out to the expected port and able to see in the debug sniffer.
