what is "Allow Incoming Echo Requests "

Below is in our configuration instructions for unattended telephony systems
running on XP. However, there is no documentation as to why.

What is Allow Incoming Echo Requests and should we care? Is it related to
support using PCAnywhere?

Control Panel, Network Connections, highlight Local Area Connection, Choose
Firewall option, Turn it On, Advance tab, highlight Local Area Connection,
Click Settings, ICMP tab, check Allow Incoming Echo Requests.


Thanks, bob

"Allow Incoming Echo Requests " permits another computer to send a "packet"
(pings) to your computer and your computer "echoes" back receipt of the
packets - verifying a path between computers. Pinging is utilized in
troubleshooting TCP/IP problems but is considered a security risk.

This setting simply allows the machine to respond to a ping command.
Enabling ICMP echo is required in a wide variety of scenarios - eg. an
Active Directory domain controller must have this setting enabled. I do not
know why it is required in this instance.
