Pag nag-create ka ng lan server at lumabas na sa UI yung server address, atbp., saka kayo sasali dyan sa server na yan using your client. You join in that lan server with the map you used, same as others who are connected to the lan. Ang gamit nyan ay hlds.exe to create a server. Yung CS clients ang makakapaglaro dyan kung sumali kayo sa live server. Yan ba yung ibig mong sabihin?
Note :Without hlds.exe in your counter-strike folder with hl.exe, clients can't can't play on lan.
