The user's B (73) and user C (10) sweat addresses are configured by the DHCPSerVer (75). When the user A (8) wants to access the multimedia file shared by the user C (74), the steps are as follows: The method of obtaining the IP address of the virtual network card (VictuaI Netw〇rk Interface Card, VNIC) (711) of the user A (71) is set to "DHCP automatic acquisition". 2. User B (73) combines the real network card and the virtual network card into one • network bridge, and the IP address of B is 192.168.1. 3* § When the virtual A (71) and user 6 (73) establish a virtual network connection, the virtual network card (711) on user A (71) will immediately issue a DHCP Request to obtain an IP address. The packets of these McP packets will be sent to user B (73) via the virtual network connection. At this time, since the virtual network card of user B (73) is in the form of Bridge, DHCP will be used. Request packet f0rward to his own DHCP Server (75). 4. In User A (71) routing table, a new rule is added. This rule sets Gateway A (72) as the destination packet must be transmitted by the real network card, and this rule has the highest priority/first. The order 'this step is to prevent errors caused by the same IP on both sides. 5. The virtual network card (711) of user A (71) is received by DHCp Sei_veK75) (192.168.1·6), so that user ^(?1) and user (73) 'In the same regional network order (192·168· 1. X), the user (8) can easily access the multimedia files shared by the user C (74) (directly connected to 13 192.168.1.50). Please refer to the eighth embodiment (a) and (b), which are schematic diagrams showing a preferred embodiment of the remote data transmission system network bridging application of the present invention, when the user A (8i) and the user B (83) The local area network ip address is the same mask (for example, 192.168.1 X). At this time, the virtual network card of user A (81) will also obtain 192. i68. ix In this way, when the virtual network card of the user A (81) is to transmit the packet to the user E (84) of the local area network of the remote user B (83), it is transmitted to the user A. (81) User D (82) on the same regional network, as shown in Figure 8 (a), therefore, a rule must be added to the routing table of user A (81) to ensure that all packets are transmitted through The real network card is sent out, *All the external packets must be passed through the Gateway. When the rules are set, the packets destined for the Gateway must be transmitted. ^The real network card is transmitted out and the highest standard is allowed. Preface, this 防止 T prevents both parties from IP phase _ will cause errors 'through this rule can be successfully connected directly into the user network of user B (10), as shown in Figure 8 (6) Show.
