Trouble Connecting to server

I've recently had a nostalgia trip of old Super Hostile CTM maps and I want to play it with my friends and show them it, So I got to working. I downloaded the Zipped Files and I put them in my world section and uploaded them, I've turned on my server in 1.2.5 Vanilla with seemingly no problems. When I enter the 1.2.5 installation on my minecraft launcher and add the server it however says theres people inside it which I know there isn't because I have the server page. I've seen anywhere from 2 - 11 people it says is in the server. When I try to connect I just get a simple Connection lost End of stream. In my server log it seems to have no problems. This is why I have come looking for answers from people smarter then me.

After reading the page it says I need a DynIP. After looking in the "Connect" area it only shows my normal IP it doesn't have a DynIP

[Edit: Nvm I found out you have to have the server on to find it]
