Is it possible to enable ICMP for a single source IP only? I've enabled it for a line quality monitor but I notice I'm also getting (not related to the monitor) lots of requests from aws in china among other places. It's not likely impacting performance but I'd like to block it anyway unless it's a bad idea.
There's a firewall rule allowing incoming ICMP, change it.

Thanks. I was just looking at that and trying to figure out what to change.
If I set Destination address to the router and Source address to the remote server sending the requests will that block all requests accept from that IP or do I have to also add something to block everything else?
You probably only have to add/hard code the source address of the pinger.
Right you are adding the source address was all that was needed. Many thanks.
