This question borders on the outrageous.

I will assume that your intention really is security and not espionage.

In that case, forget about packet snooping and get a smart router
or gateway that does packet filtering.  You have every right to
restrict access to and from your domain in any way that you wish,
but keep your nose out of those packets -- it has no business 
being there.
