While u see the X/18 of user in yr dedicated server is not meant that there will be 18 players enter yr game.

By the default setting of valve, the coop game of L4D is only 4 players can join yr server to play the game. The versus game is max. of 8 players. Thus u don't hv to worry about too many player join yr server.

By the way, did u add the plugins in the addons file?
