Here is some info about port 53:

Lately when I check my incoming log on my router, I have anywhere from 10 to 30 people trying to access port 53 at the exact same second. This has been happening a lot lately. What exactly are they trying to do (trying to shut down my router?), and what can I do to protect my self from what they are trying to do. I do have every port on my router closed.
