Create an Inbound ICMP Rule
To allow inbound Internet Control Message Protocol (ICMP) network traffic, use the Windows Defender Firewall with Advanced Security node in the Group Policy Management MMC snap-in to create firewall rules. This type of rule allows ICMP requests and responses to be sent and received by computers on the network.
To complete these procedures, you must be a member of the Domain Administrators group, or otherwise be delegated permissions to modify the GPOs.
This topic describes how to create a port rule that allows inbound ICMP network traffic. For other inbound port rule types, see:
To create an inbound ICMP rule
Open the Group Policy Management Console to Windows Defender Firewall with Advanced Security.
In the navigation pane, click Inbound Rules.
Click Action, and then click New rule.
On the Rule Type page of the New Inbound Rule Wizard, click Custom, and then click Next.
On the Program page, click All programs, and then click Next.
On the Protocol and Ports page, select ICMPv4 or ICMPv6 from the Protocol type list. If you use both IPv4 and IPv6 on your network, you must create a separate ICMP rule for each.
In the Customize ICMP Settings dialog box, do one of the following:
To allow all ICMP network traffic, click All ICMP types, and then click OK.
To select one of the predefined ICMP types, click Specific ICMP types, and then select each type in the list that you want to allow. Click OK.
To select an ICMP type that does not appear in the list, click Specific ICMP types, select the Type number from the list, select the Code number from the list, click Add, and then select the newly created entry from the list. Click OK
On the Scope page, you can specify that the rule applies only to network traffic to or from the IP addresses entered on this page. Configure as appropriate for your design, and then click Next.
On the Action page, select Allow the connection, and then click Next.
On the Profile page, select the network location types to which this rule applies, and then click Next.
On the Name page, type a name and description for your rule, and then click Finish.
