FINE! 
Ok, installed l4d no issue but once the server is up I can not join it unless I set "sv_lan 1". That makes it so other people can't join from the internet right? (Answered)
How do I set it up so I can join the server?
Any Mani-like plugin for l4d? (Answered)
Using the GUI what are "Variable" and "Value" for?
What Ports need to be unblocked? Just 27000-27015, 1200-1200, 27020-27039? (Server ip: 68.58.208.132:27015) (Answered)
