I see similar entries in my log file too. Here's a sample:

I have no idea what to make of the DoS attacks. Nothing seems to be affected, best I can tell. Everything seems to be running normally with no known issues.
When I Telnet'ed into Orbi to try and prevent future auto firmware updates, one of the three nvram variable was not set to the expected value. Here is what I found:
orbi_auto_upgrade=3404316802
auto_check_for_upgrade=1
auto_update=1I was expecting the first variable to be set to 1 like the other two. From what I have read on this forum, to turn off auto updates, we change the values from 1 to 0. Does it matter that the first variable is not set to 1? Is it safe to set it to 0?
