Hi,
noticed this behavior:
- XG configured for 3 DNS servers
- on upstream device only those 3 DNS servers are allowed for XG
- occasionally XG sends DNS request to many other DNS servers and these are denied by upstream device
- issue on 18.5.1 and actual 18.5.2 too (observed that on prior versions too)
- XG running as MTA and web proxy only
- when looking to such requests, that were PTR queries only
Not sure what triggers this behavior during operation.
I was able to replicate this behavior when cable was plugged out and then back in to the device.
