This makes the PPP peer computer (the computer you are connected to with your modem) to act as a gateway. Your computer will send all packets not going to a computer inside your local net to this computer, which will route these packets. This is the default for most ISPs, so you should probably leave this option on.
Gwna hyn i' r cyd- gyfrifiadur PPP (yr un sydd wedi' i gysylltu â' ch modem) ymddwyn fel all- borth. Bydd eich cyfrifiadur yn anfon pob pecyn nad yw' n mynd at gyfrifiadur tu fewn i' ch rhwydwaith lleol i' r cyfrifiadur hwn, a fydd yn cyfeirio' r pecynnau hyn. Dyma sy' n rhagosodedig ar gyfer y rhan fwyaf o ISPs, felly dylech, mwy na thebyg, adael y dewisiad yma ymlaen.
