Irene,

This depends on what your pinging. What(where)
is the client/system your trying to ping?

Your rule says any _internal_ machines are
allowed to repond(which it s/would by default.)

If your pinging an outside machine, then you need
to change your rule to allow the return packet from
that/those machines.

Does this make sense? If not, write back.

Robert
