[WindowsFirewall.icmpsetting_name]
The [WindowsFirewall.icmpsetting_name] section contains entries for configuring Windows Firewall.
The default configuration for Windows Firewall blocks all Internet Control Message Protocol (ICMP) message types; however, you can modify this behavior by adding entries to the Windows Firewall Exceptions lists that enable certain ICMP message types.
The permitted values for adding ICMP Message Types to the Windows Firewall Exceptions list are described in the following table:
| ICMP Message Type | Number | Description |
|---|---|---|
OutboundPacketTooBig |
2 |
When an Internet Protocol version 6 (IPv6) packet is too large to be forwarded, data is dropped and a computer replies to the sender with a Packet Too Big message. |
OutboundDestinationUnreachable |
3 |
Sent data that fails to reach this computer due to an error is discarded and reported with a Destination Unreachable message explaining the failure. |
OutboundSourceQuench |
4 |
When a computer's ability to process incoming data cannot keep up with the rate of a transmission, data is dropped and the sender is asked to transmit more slowly. |
Redirect |
5 |
Data sent from a computer is rerouted. |
InboundEchoRequest |
8 |
Messages sent to a computer are repeated back to the sender. This is commonly used for troubleshooting. |
InboundRouterRequest |
9 |
A computer responds to router discovery messages. |
OutboundTimeExceeded |
11 |
When a computer discards a packet because its hop count was exceeded or it ran out of time to assemble fragments of a packet, it replies to the sender with a Time Exceeded message. |
OutboundParameterProblem |
12 |
When a computer discards data that it has received because of a header problem, a reply is sent to the sender with a Parameter Problem error message. |
InboundTimestampRequest |
13 |
A confirmation message is sent, indicating the time that the data was received by a computer. |
InboundMaskRequest |
17 |
A computer listens for and responds to requests for a network subnet mask. |
