Correct setting for "Disable port scan and dos protection" in C3700

Hi Expert,

What should be the correct setting for "Disable port scan and dos protection" from 

Advanced>WPS Wizard>Setup>WAN Setup

After I did a factor reset, The box is checked in "Disable port scan and dos protection".

I see from Log all the time that have these entries:

[DoS attack: Teardrop or derivative] from 139.12.155.0, port 0 2
[DoS attack: Ping Of Death] from 139.12.155.0, port 0 2


Should I un-check the "Disable port scan and dos protection"?
My device is Netgear C3700 Cable Modem Router with WiFi
Thanks for your help.

Frank

    Yes you will want to un check the box so it is enabled.
