Computers under the same network - same external IP?

[extremepilot]

When several computers share an internet connection, in this case there is a network of computers connected using a wireless router, share an internet connection, do they all have the same external IP?

And what's the correct term for the computer that is physically connected to the modem? A Gateway?

Yes and yes.

However, a gateway is a computer (or router) that other computers connect to in order to access the Internet.

and to Complicate this a little more, the protocol that the Gateways/Routers normally use because it's probably the easiest to setup (espically the non managed variety of Routers) is NAT (Network Address Translation).

To confuse you even more, the type of NAT most home routers use is SNAT, or Source Network Address Translation, allowing multiple private machines to use a public IP address. When you publish a service on an internal private machine to the web (or create a one-to-one NAT for a specific private machine), you're doing what's called a DNAT, or Direct Network Address Translation.

Fun, eh? Probably not useful to you, but it might be someday .
