I have ping disabled directly on my router so none of the machines
behind it can be accessed from outside.

Why wouldn't you do it there?

A possible answer is that you are using the laptop truly mobile but
that would be the only need for such a mod imo.
For those that 'know' is there any other scenario where you might want
to disable ping access on a machine basis?
