my DNS on rhe USG is configured as shown in the screenshot and in my mind, the USG send DNS requests to the next hop (INAC Firewall).
Are there FQDN's for the required traffic from USG to Extranet/Cloud resources availible at ZyXEL, that can be limited the traffic to ZyXEL dedicated ressources and not to destination = ANY ? and can the lLOG reduced by disableing the LOG entries to reduce SYSLOG server volume by unwanted informations ?
Thx forward and best regards
Here is the list of IP/FQDN and ports of myZyxel.com, UTM and SecuReporter service.
The log for SecuReporter cannot be turned off unless you turn off system log, but all other system logs will also be turned off.
