On the other hand, how many devices realistically need to be accessible from the outside by default in a typical setting (ie: in a home/small office)? On a network you have several classes of devices:
1. Devices that frequently need to run an server or peer to peer connection that requires outside access (ie: servers, some computers, tablets, phones, gaming consoles, VOIP phones, etc)
2. Devices which might need to be accessible from the outside in a few cases, but generally speaking have no need to be accessible from the outside (ie: most computers
3. Devices which generally have no need to be accessible from the outside (ie: NAS, network printer, security camera, security system, phone system, etc)
