شركة فورتي جيت تنصح بتغيير DNS الاساسى الخاص بها باخر مثل 8.8.8.8
او استخدام Local الخاص بك من Internet Service Provider
حيث الافتراضى هيسبب ضعف و تقطع فى dns فهو غير مخصص للتصفح ولكن له استخدامات اخري
لذا قم بتغييرها ثم هيا بنا نحل مشكلة DNS Error" in Forward traffic log
ان الدى ان اس على Switch Interface على سبيل المثال 192.168.1.1 لا يعطى انترنت اى DNS
حيث انه يجب ان تفعيل DNS Server من داخل الفورتي جيت ثم تسمح لهذا Interface بعمل ايضا DNS
اقتباس:
If you do not change your FortiGate unit default DNS configuration, FortiGate-initiated DNS queries can fail.
DNS queries that fail can cause address resolution problems and can also cause the FortiGate unit and FortiGuard AntiSpam to identify legitimate email as spam.
FortiOS on all FortiGate units includes a default DNS configuration. Most users should change this default configuration to avoid DNS lookup failures.
The default FortiGate DNS configuration assists with resolving FortiGuard Service addresses and for other DNS requirements during the installation of your FortiGate unit.
DNS resolution can be seen to fail.
Configure a DNS Server for the interface that DNS requests will be sent to.
Set the mode to "Forward to System DNS".
DNS resolution can now be seen to be successful.
