Embodiment

[0018] The LAN side port of the home gateway provides the NAT network address translation function. In the LAN port settings, the specified IP address pool can be configured to assign the same network segment address to the network device connected to the LAN port. The home gateway implements address allocation through the DHCP Server function, allowing users to quickly access the network without manually configuring the network IP, subnet mask, and DNS server.

[0019] The present invention provides a method for intelligent network access of terminals on the LAN side, which is used to realize whether the ports on the LAN side respectively control whether to support the DHCP function, which requires the DHCP Server application layer to know that the DHCP DISCOVER broadcast message received from the LAN side is from Which physical port or SSID, and whether the physical port or SSID enables the DHCP Server function.

[0020] The format of the DHCP message is shown in Table 1, fr...

Abstract

The invention discloses a method for realizing intelligent network access of an LAN side terminal. The method comprises the following steps: receiving a Client DHCP DISCOVER message by an LAN side; enabling the network bridge to analyze the DISCOVER message and update the MAC address learning table; after the DHCP Server receives the DISCOVER message, acquiring a Client MAC address and network bridge name information, querying user configuration information, and matching the MAC address with the physical port name, inquiring whether the physical port starts a DHCP Server function, if so, replying a DHCP OFFER message by the DHCP Server, allocating an available IP address, and otherwise, losing the message to realize a function of forbidding automatic IP address allocation. Therefore, the equipment accessed to different ports on the same LAN side can select to automatically obtain the address or configure the static IP address through the DHCP.

Description

technical field [0001] The invention relates to the field of network technology, in particular, it is a method for realizing intelligent network access of a terminal on the LAN side. Background technique [0002] With the rapid development of the home Internet of Things, there are more and more smart devices, and the number of smart devices (smart home appliances, mobile phones, smart switches, smart cameras, etc.) that need to be connected to the home gateway is also increasing. Different smart devices also have different requirements for the way of assigning IP addresses. Usually, home gateways use DHCP or static methods to assign IP addresses to devices accessing the gateway. This unified control gateway will give all access The IPs of the devices are all allocated on the same network segment, so there will be certain limitations. For users with special needs, for example, if you need to build a mixed network environment where different LANs are mixed together, you need ...
