I do not understand this ICMP activity being blocked by my Firewall on default. Perhaps some kind person conversant with this matter will respond and enlighten me.
My Firewall blocks these pulses by default. Although I can customize the settings and remove the blocking of ICMP traffic, since I regard my FW suppliers as knowing best, I see no reason to alter their settings. I have entered my IP as being "Trusted" in the hope that these pulses will stop being logged, but it has made no difference. They are blocked every few seconds, which makes an awful lot of FW event logs. They seem to be "Echo requests", which means nothing to me except it infers meaningless activity.
My settings are shown on the two screen shots : 1 - the settings table and 2 - the event log after a few minutes browser use.
