Im running a MC Sharp server, and I cant connect to my server with the external URL. I can connect using the lan address for minecraft, but otherwise I cant get in. One of my friends was able to connect, but my anti-grief system kicked him, and now he cant get back in. I checked and made sure he wasnt banned, and he isnt banned. I had another friend try and connect, and he cant get in either. I checked my server and its running fine, no errors. I have all the correct ports forwarded, and no firewall/antivirus. My server ran fine a couple weeks ago, and I could connect with no problem.

Also, the World of Minecraft client barely connects half the time, and runs pretty damn slow. I have the latest version of it, and it worked fine a few weeks ago. Im not sure why nothings working today. I havent changed anything since I last ran all this. Any help would be appreciated.
