Server help

Ok so i have been trying to make my own dedicated server for a while now and i have managed to get preety far twice and both i have just hit like a brick wall in my way the first time was when this happend in an earlier post http://www.facepunch.com/showthread.php?t=752247 and so then i tried again last week with this video http://www.youtube.com/watch?v=RBWarFW305I and i got to the point were i can start my server, i can join ,nobody else can and it wont show up online either even with sv_lan 0 and heartbeat (btw i am trying to make an rp server and i cant run darkrp it says connot exec server.cfg)

im making srcds server
im using external ip (im joining with mine,i also have a static ip)
i have opened all the ports i need

so if you know anything about this, have any tips or links that can help me please post em
