Yup, looking at all the stuff that's slammed against your router can be scary, but knowing what's going on is a good step in maintaining control of your network.

Are you running just a single NIC, or dual?

If single, they yeah, you're going to see that happen.

If dual, then you need to tweak the config of your Internet side NIC. It should be TCP/IP Only. No WINS, No NetBIOS. There's no reason for the wild side nic to do anything but send and receive traffic for the services you have enabled/exposed to the outside. Mail, Web, VPN, etc.
