I came accross this great article about how to block the ping traffic with IPSec.
The patch was required as I noticed in the HackerSafe reports for one of the clients that this is happening with the server, and thus the need to fix it.
I didn't knew much about this issue until it came in the reports and the article basically lays it out clearly on how to block it.
The steps mentioned in the article and the thumbnails provided were great help.
Thanks Daniel Petri for the article.
