My question is about ping request. I want to block ping request if it
comes from outside and I want to be able to ping other hosts.In other
words, I want to block all ping request one way only.

How can I do that? I have been already tried to do something with IPSec,
TCP/IP filters etc.
If there are anyone who know how to to do this, please tell me the way.

Thank you
