Hi @Steve61 

Thanks for bringing this to our attention. Would be helpful if you can take a look at this: Solution to ER605 V1 1.3.0 Firmware Got Many Logs of "TCP no-Flag attack" Issue

It will be optimized in the future update.

May I know whether these logs affect the actual usage of your network?

Have you tried to disable the Block TCP Scan (Stealth FIN/Xmas/Null) option for testing?

Is there any Amazon service in your network that has the interact behaviors with Cloud servers?

  @MrHC1983 

 

Since updating my ER605 V2 to firmware 2.2.0 (rel 64012) I have also been receiving these log entries. They appear to be coming every 10 minutes and 5 seconds, like clockwork.

 

My ISP speeds don't seem to be affected, but I haven't timed a speed test to coincide with these events.
