It appears our DNS server is accepting recursive DNS queries that are being abused to create denial of service attacks

Hello,

We have been notified that our DNS server is accepting recursive DNS queries that are being abused to create denial of service attack.  I am not seeing anything obvious in my DNSDHCP tool on how to resolve this.

We are running SLES 15sp4 and OES 2023.0 (we are planning on updating this in a couple weeks).

Temporarily our service provider has placed some acl on their system to block this, but asked that we fix it.

Thanks for your help.

Gene
