You should only need to configure a proxy server if your network administrator requires it (if you are a dial-up user, that would be your internet service provider or ISP). Otherwise, especially if you are feeling a bit confused about this proxy business, but everything seems to be fine with your internet connection, you do n't need to change anything.
Tan sols hauríeu de necessitar configurar un servidor intermediari si l' administrador de la vostra xarxa us ho demana (si sou un usuari de la línia telefònica, aquest seria el vostre proveïdor de serveis d' Internet o ISP). D' altra manera, especialment si us trobeu confós al respecte, si tot sembla funcionar correctament en la vostra connexió a la Internet, no necessitareu canviar res.
