I've been trying to set up a minecraft server on PC for me and my friend for a while now, I've downloaded the server, made sure all the settings are right in that, I've checked and my 25565 port is open using www.yougetsignal.com/tools/open-ports/ and when I put this on to 'add server' it says 'can't reach server' and yes I do have the white server box open when I try this, any help will is good help at the moment, thanks :)

Ps im playing on minecraft 1.0.0 on windows 7 PC and my Internet comes through a BELKIN modem router and my provider is TalkTalk
