text: manage my dsl internet connection sharing.? i have a dsl connection and i share it with another system. i want to disconnect it without unplugged lan wire & without unchecked my dsl connection to sharing i.e without change ip address on server system. i assume you don't have a dsl router - which would be the best solution.  if you want the client machine to stay connected to the internet, you have to keep the server machine connected to dsl and keep sharing the connection. alternatively, you could just plug that client machine into the dsl, but you'd have to set it up to login or whatever and, if you have some sort of dsl modem, you may need to restart it.  of course, that opens your second machine up to the usual internet dangers of port scanners and such.  like i said before, the best thing would be to get a dsl router that connects to the dsl where you could connect any machine to the dsl without it being dependent on any other machine, and you can set up the router to open certain ports so that a web server or quake server can still work.
