Answered my own question:

Today I noticed another string of access attempts to (this time) udp port 11608 and 53. Then it occurred to me that I must be receiving packets meant for the previous owner of my dynamic IP. I confirmed in the firewall log that all the hits started after my modem had reconnected.
