We want to click anywhere we like and not get infected evne if we know
this is a trojan. See? Stateful Packet Inspection against any kinf of
malware would be very safe even if the user deliberately open a infected
link or attachement.

We must find a way to do this without paying $4500 for hardware firewall
appliance! :-)

If the service that is listening to port 1000 have some kind of
vulnerability, otherwise its safe.
