   What, exactly, was in your log?  Copy+paste is your friend.

   "ADVANCED > Security > Block Services" stops users on your LAN from
accessing services on the Internet.  It does nothing about external
access to devices on your LAN.

 

   Without seeing the messages from your log, it's hard to be sure, but
I'd guess that your router is already blocking the "attack" (if it's not
just a false alarm).

 

   Other than the annoying messages in the log, are you seeing any
actual problems?

   A port number like that refers to the port on the remote (attacking?)
system, not anything on your router.  It's meaningless at your end.

 

   Don't worry; be happy?

   As suggested before, these log entries do not mean that anyone is
getting into your modem.  Even if these were real attacks, and not just
false alarms, you're seeing less than one per hour. I doubt that
they're causing your problem, whatever it is.

 


   Start again.  Describe your actual problem.  Then both you and your
readers can worry about what might be causing it.

for Documentation.  Get the User Manual (at least).  Read.  Look for
"Troubleshoot"?
