Tcp Port 1025 Blackjack

Is this anything to worry about?
As of now, I have 10 megs of the following logs, and still climbing.

I have no idea of what they’re trying to do, but UDP ports 53 and 1025 (blackjack) seem to be of interest. The kicker is, these ports are not open on my router, so how are they seeping through, and why? I recently setup a caching name-server, which uses port 53, but again, I don’t have that port open on the outside.
Iptables is dropping the packets, but that because I’ve blocked their class C. My question is, are they somehow using my name server, or is this type of probe common? Should I close off these ports, and how?
Thanks,
Dave H
