Reverse DNS requests from standby gateway every 6 hours

Hello community.

We have observed that a standby member sends Reverse DNS requests towards DNS server every 6 hours for different IPs.

Any idea why this is happening?

BR,

Kostas

The only reason I can think of for reverse DNS lookups is non-FQDN objects in the policy.
Any of those present?

Hello PhoneBoy

Yes they are present if you mean host1 with IP 192.168.1.2 and not DNS entries either forward or reverse.

We are not using domain objects.

BR,

Kostas

It's a specific type of object (not a standard host/network object):

If you don't have any of those, not sure offhand and it might be worth a TAC case to ask.
