Depending on which type of router you're using this is a good place to start:

Are there some sort of guidelines on what should be blocked on an
Internet-router? RFC 1918 addresses and TCP/UDP-ports 137-139 are of
course well-known, but is there anything else that is recommended or
perhaps even required? I had a faint memory of seeing something about
this on ISOC's homepage but found nothing. Anyone with ideas?
