USG40W / Security Policy Control Match default rule, DROP 192.168.0.1 224.0.0.1 ACCESS BLOCK

"Security Policy Control Match default rule, DROP 192.168.0.1 224.0.0.1 ACCESS BLOCK"

I am having this line coming up in my log almost every 2 minute. My firewall is setup almost default. I understand that this could be something about firewall blocking DNS responses.

How can I modify the Security Policy to get rid of this. Or is it necessarily to do anything?

Thanks for your help!
