Port scanning question - What to do?

[AU Tiger]

I always notice the data light on my cable modem is constantly flashing (even when all computers are off). I enabled logging on my BEFSR41 and this is what it logged in less than a minute. Is there anything I can do with info? The ISP is Road Runner on Time Warner.

Incoming Log Table
Source IP Destination Port Number
81.56.217.126 4662
80.201.208.17 4662
80.33.164.222 4662
158.39.24.76 4662
and many more, probably about 50+ all going to ports 4662 and 4665

Should I set anything in the router to handle the port being scanned, like forward to an nonexistent IP?

Edit: Damn, didn't mean this to go in Off Topic, meant to go to Networking.

Do you use eDonkey? Is your IP dynamic or static? If the former and you haven't installed eDonkey, most likely there are hosts that are simply trying to connect to what used to be a valid eDonkey host.

And no, you don't need to do anything with the router for the port (it's most likely not being scanned). The firewall is simply logging the attempt, but it will drop the packet on its own.

i.e. Don't worry about it... unless you have that port open

that is overnet and it is by the same company, edonkey.

That would make sense, I had a eDonkey running earlier and didn't think about that. I figured it was something different.

Nothing to worry about at all.
