Well, like I said before, this line was enough to pique my curiosity and
get me to look at the router's logs. Sure enough, they showed that I was
indeed being attacked. I have since cleared the router logs, so I can't
post their contents, but suffice it to say that there were multiple
attempts to break in over a 10-minute period. BTW, regarding your attack:
