Allowing incoming ICMP from only a specified source IP

Question

In the predetermined snippet:

netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" 
protocol=icmpv4:8,any dir=in action=allow

What would I change exactly to allow incoming ICMP only from a specific IP:

# assuming I want incoming pings from 192.168.1.5 and I use: 
remoteip=192.168.1.5

What exactly should my new command be?

Answer 1

For allow rule from specific ip(s) or subnet you can add this argument : remoteip

For your situation :

netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request from X.Y.A.B" protocol=icmpv4:8,any dir=in action=allow remoteip=X.Y.A.B

X.Y.A.B is the ip address where you wish to authorize ICMP use to your machine

you can have more information with :
