A virtual internet protocol (IP) gate, between a legitimate internet and a virtual internet, can reuse the internet address in a specific range of the legitimate internet addresses for resolving the insufficiency of IP addressing. The virtual IP gate at least comprises a connection module, a selection module and an address conversion module. The connection module establishes connection with the virtual internet by using at least a virtual internet address and establishes connection with the internet by using at least an internet address with the address not within the aforementioned range. The selection module corresponds to a selection port number and receives a transmission packet from a processing module on the legitimate internet to the virtual internet when establishing the connection (including connection-oriented connection and connectionless connection), wherein the &lt;source address: source port number&gt; and &lt;destination address: destination port number&gt; of the delivery packet are the &lt;processing internet address: processing port number&gt; of the processing module and the &lt;internet address of virtual IP gate: the selection port number&gt; of the selection module. Besides, the selection module, in response to a source console, notifies the destination console on the virtual internet of all console names, and transmits the delivery packet to the destination console according to a console selection signal provided by the processing. And an address conversion module is used for converting the addresses between the legitimate internet and the virtual internet.
