Is there a program that can make a LAN connection through the internet?

The type of network your asking about is called a VPN (Virtual Private Network) or a VLAN (Virtual LAN). A VLAN acts like an ordinary LAN, but connected devices don't have to be physically connected to the same segment.

LogMeIn Hamachi lets you setup a virtual LAN connection on both PCs and Macs through the internet. The software is free for non-commercial use, never expires, and will let you set up your virtual LAN connection in less then 10 minutes.

How do you interconnect two networks in the same geographical area?

It all depends on this geographical area. You could use two wireless routers. Given the distance isn't too far. 2 linksys routers with ddwrt firmware, put one both networks and that will be a good job.

If it is far, you could be looking at running a wire from one network to the next.

If neither of these are feasible you could look into VPN's.

Where is the wireless tab on a router?

The Wireless 'tab' usually refers to the software that controls the hardware.

If you open 'Network Connection' and right-click on the 'Wireless Network Connection' and select 'Properties', one of the 'Tabs' shown on the screen will be for 'Wireless'. The tabs are meant to remind you of the tabs in a manila folder.

For example, on the screen I am looking at now, there are 'tabs' at the top labelled 'Answer', 'Answer it!', 'Discussion', 'History' and 'Contributors'.

I hope that makes some sense to you.

Which type of Network Address Translation allows a host on a public network consistent access to a specified private inside host?

There are three different types of NAT (Static, Dynamic, and Overloading). The one you're most likely talking about is static NAT. It provides a one to one mapping.

Can you use NAT to assign an internal IP to a DMZ proxy server or does the DMZ proxy server need a static IP so intranet PCs can access the proxy?

As long as you don't need a domain name, you don't have to have a static IP. Having a dynamic IP just means that you'll need to check what you're IP address before each time that you want to use the proxy, since it might have changed since last time. So just go into the router config and set the DMZ to the computer that hosts the proxy server and then go to a site like www.IPaddress.com to find out your external IP address and then just type that in as the proxy when you're using the intranet PC. -DJ Craig
