  • Support for BIND DNS has been removed from Plesk for Windows due to security and maintenance risks.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS.

Port 53 DNS DDOS

KrazyBob

Regular Pleskian
My Firebox X8000 is showing line after kine after line of three servers out of over 100

xxx.xxx.xxx.xxx 208.67.222.222 dns/udp 1-Trusted 0-External denial of service attack, drop this packet.

I cannot find any setting in Plesk that will.l stop this. Running lsof -i :53 shows me that every IP assigned to the server is pinging out. Webalizer appears to also be running, as if doing a hostname lookup. I did not set this in Webalizer and don't know how to check or turn it off.

How do I stop my irewall from rejecting DNS outbound as a ddos when it is legitimate traffic? If Webalizer is ausing this, how and where do I turn it off. I recall that Webalizer has a setting just as AWStats does for full hostname lookup.
