DNS Attack

Hi,

since 5 days i have a DNS Attack on my router.

I see it in the traffic Queues and on the firewall connections:

Anyone an idea to fix it ?

please search the forum for topics on how to protect your services (like DNS), your router via firewall. Or check wiki for default firewall (if your router did not come with default configuration) and adjust it to for your setup.
