The easiest form of a DOS Attack is content simply requested from a visited website, such as a web page, a file, or a search engine.
When you have your log set to log those, you will always get a lot of them. Google, Microsoft, various websites, etc. will more than likely be most of them. I randomly checked some of your logged DOS attacks. Some were Microsoft, Google, Russian Federation, Amazon.
I only have these 3 items checked: <-- I'm not saying this is what you or anyone should have checked as well.
Attempted access to blocked sites and services
Router operation (startup, get time etc)
Port Forwarding / Port Triggering
