Default Routers and NAT

Sorry I'm a bit of a noobie.

Do you only need to configure NAT if you need incoming connections to come
to a certain machine (eg. mail server/http server) and not say if you play
Counter-strike.

What happens if you have 2 PC's connected to a router and you play
Counter-Strike on just one or both PC's. How does everything know where to
send the right information? Does this use NAT in any form?

Thanks in advance...

What is NA(P)T?


Network address port translation - where the router/switch/whatever can take
connections from outside on your external IP and send the data to an
internal IP on a different port (different port optional).

....I think...

To answer your question, every packet of information that you sent on a lan
or intranet/internet has IP header information. Its this header information
that contains the destination address. If your lan is setup with a typical
192.168.x.x style adressing then any header info that starts 192.168.x.x is
for the lan, anything else your router will send to ythe internet. Its a
lot more complicated than that, but thats the general principles.
