web hosting buy&review&best Q&A

I have joined networks and also created networks in hamachi successfully.
Also i have played with people .
but i could only join lan server hosted by some other people
whenever I hosted a lan server no one could detect my lan server
do i have to download some extra file for hosting and not joining lan server.

I currently am running a MapleStory private server, and hate leaving my pc on. Is there a way of keeping the server running and the pc off?? If you would please list the options from highest pricing to lowest pricing, it would be deeply appreciated
