Bizarre DNS results? 198.18.x.y returned

Hi there,

I'm getting something odd happening which I've never seen before, I am intermittently getting DNS queries answered with a 198.18.x.y address.

Using Fortiguard or local DNS servers doesn't make any difference to the behaviour.

It happens with both local clients and through the CLI on the box.

For instance:

Have to say I've no seen that before!

Any ideas?

Thanks,

Jon

Is the Fortigate's WAN(s) interfaces configured/set to override internal DNS?

Could you paste ASCII results from the query? Pictures don't quite work.

And to add, you can diag sniffer packet any "host x.x.x.x and src port 53" to see the DNS-answers
