I edited the description a bit. All I did was add a sentence, fix some grammar, and rearrange some of the sentences.
I do have a question about where it say:

When I first read this I thought "private" was referring to using a private IP address but when I saw the picture under "Configuration" it has a public IP address. Can this forward to a public IP?
