what are NAT settings and where do you find them?

Answer 1

NAT - network address translation is used in routers for conversion between local addresses and internet addresses.

If you are connected to a router you probably have an IP address like 192.168.0.x or 192.168.1.x or 10.0.0.x etc
These are non routable local area addresses. When you go to the internet to a website, that website will have a "public" or routable address. Just like your router will normally have a routable address from your ISP. The job of translatting traffic from the routable to non routable address is called NAT.

You can also just do a Google search for netwok address translation, or NAT to find out the entire details.

Answer 3

You will find these in any proxy server you use, usually, to access the internet. You will also see them in your router (linksys, netgear etc) which present a single IP address to the provider but do the translation so you can connect several computers to use that single broadband connection
