[Pdns-users] PDNS Authoritative Server DDOS Protection

[Hamed Haghshenas]

Hi,

 

I'm using PDNS Authoritative Server 4.1.3, today I see my server not
response and error or timeout on resolves .

When check the server see to many DNS requests from some IPs from Brazil
like DDOS attack. To fix errors and timeouts, I block the attacker subnet in
my firewall .

 

Now could you please let me know how protect my server from DOS and DDOS
attacks ?

 

Best Regards,
