[0002] With the development of society, people have higher and higher requirements for home automation and networking. However, the current remote access technology is mainly used in public places and enterprises, and its application in homes is limited.
At present, there are inconsistencies in the interface and protocol specifications adopted by the remote network communication platform. Therefore, different clients need to be set up for different platforms (including purchasing client hardware suitable for different platforms and developing client operations suitable for different platforms) software), which will undoubtedly increase the complexity of the operation and cause a waste of resources

specific Embodiment approach 1
[0052] Specific implementation mode one, combining figure 1 Specifically explain this embodiment, the remote network access support system, including:
[0053] Data transceiver module 1, the remote network access support system performs data transmission between the data transceiver module 1 and the remote network access client;
[0054] Packet filter module 3, connected to data transceiver module 1; for judging whether the data packet received by data transceiver module 1 needs to be filtered, and subsequently converting the destination IP address of the data packet that does not need to be filtered to a preset standard IP address , and output packets;
[0055] The forwarding module 4 is connected to the data packet filtering module 3, and performs data transmission between the data transmission end of the local area network and multiple network devices in the local area network; it is used to send the data packets output by the data packet filtering module 3 to the correspo...
specific Embodiment approach 2
[0058] Embodiment 2. The difference between this embodiment and the remote network access support system of Embodiment 1 is that the data packet filter module 3 includes: a judging unit 31 and an address changing unit 32,
[0059] The judging unit 31 is connected to the data transceiver module 1; the judging unit 31 receives the data packet sent by the data transceiver module 1, and judges whether the data packet is a data packet under the UDP protocol: preset judging conditions:
[0060] If the data packet is a data packet under the UDP protocol, then judging unit 31 continues to judge the data packet; if the data packet is not a data packet under the UDP protocol, then judging unit 31 filters the data packet;
[0061] Subsequently, the judging unit 31 judges the network port corresponding to the destination IP address of the data packet:
[0062] If the network port is port 80, the judging unit 31 sends the data packet to the address change unit 32; if the network port is no...
specific Embodiment approach 3
[0064] Embodiment 3. The difference between this embodiment and the remote network access support system in Embodiment 2 is that it also includes: a marking module 2,
[0065] The marking module 2 is connected between the data transceiving module 1 and the judging unit 31 , and is used to set a setting mark on the header of the data packet sent by the data transceiving module 1 , and send the marked data packet to the judging unit 31 .

Abstract
The invention relates to the field of network communication, and discloses a remote network access support system and a remote network access method. In order to solve the problem of inconsistency in the interfaces and protocol specifications adopted by the remote network communication platform, different platforms need to set up different clients. The remote network access support system of the present invention performs data transmission between the data transceiver module and the remote network access client; the data packet filter module is connected to the data transceiver module; it is used to determine whether the data packets received by the data transceiver module need to be filtered, Then convert the destination IP address of the data packet that does not need to be filtered into a preset standard IP address and output it; the forwarding module is connected to the data packet filtering module, as the data transmission end of the local area network and multiple network devices in the local area network. Transmission: used to send the data packet output by the data packet filtering module to the network device corresponding to the standard IP address. The invention is suitable for network communication.
