Is this something I should be worried about?

Or is someone trying to hack in?

Hmm I would log into your router and blacklist those IP addresses from connecting.

Ummm... isn't that what it's doing already? After all, it has to inspect the packet to know it's source address (connection), then drops the packet or closes the connection.

It shouldn't be a problem since the router is blocking it. I'd check the logs for a day or two and make sure it stops. If it doesn't stop or starts effecting performance, you can try contacting your ISP, or the ISP that holds those addresses. they may be able to help you.
