Someone on address xxx.xxx.xxx.xxx wants to send ICMP packet to your machine?

application tcpip.kernal driver

Anyone know what this is? the IP address resolves to
serial1-10.xxx.xxxx.alter.net. I keep getting the same request over and over
again

Thanks

Thanks Lawrence,

I figured it out finally. It is Kerio. Every time the Kerio open connections
windows is open, I am constantly getting the alert message: ICMP [3]
Destination Unreachable from 157.130.72.29 was blocked by rule 'Incoming
ICMP'

Whether this is the way it is 'posed ot be I have no idea. But it is
annoying.
