There are 2 different IP addresses. The WAN (Wide Area Network = Internet) and LAN (Local Area Network). The 59... address is the WAN. Each of your machines has its own address 192.168.x.y

In order to offer a service from your machine to the whole world, your router has to do know to which of your local machines to send the data. This is called 'port forwarding' and there will be a control panel on your router for this purpose.

I've written an article about this: http://clanmills/articles/portforwarding/

I recommend you get a Dynamic DNS name. My WAN IP address changes every day however my dynamic name '' is fixed. There's more information about this in the article.
