Use Domaintools.com whois feature to see what those IP addreses are coming from. Contact our ISP about changing the WAN IP address that the modem is passingthru and blocking.
It's just the router reporting what it's detecting and blocking. It's doing it's job.

Thanks. I called ISP they said they can't do nothing with this, but you confirmed that at least my router is just doing its job. That's fine. Many thanks again.
Often DoS attacks are just usual Internet white noise that your router is designed to block. So as your ISP advised, this is just a good sign that the router is doing its job.
