I have been googling all day for a comprehensive set of instructions that will allow an Arduino with Ethernet Shield to be visible to the whole world versus just being visible to my local area network. I did this example:

but of course it only works with a local connection. I would like to be able to access my arduino remotely from anywhere but there doesn't seem to be a lot on the web about it. I have a cable internet modem connected to a linksys E1200 wireless router. I have found a few things that I don't understand very well such as dynamic dns and port forwarding and I am sure that I have found some of the pieces, but I just don't know how to put them together. Can someone help me out with this?
