Abstract
Multiple simultaneous network connections from a single PPP connection may be accomplished by utilizing a gateway in the following manner. A first network connection is established between the gateway and a first network. A first real network address for the user is then received, the first real network address assigned by the first network. Then, the gateway may establish a network session between the gateway and a second network and receive a second real network address for the user, the second real network address assigned by the second network. A virtual network address may be assigned to the user for network address translation purposes. Additional network connections may be added in a similar manner. Network address translation is then performed on packets traveling between the user and any of the network sessions. This allows each of the simultaneous network connections to gain the benefits of network address translation.
