Detailed ways

Hereinafter, the present application will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.

It should be noted that the terms “first” and “second” in the specification and claims of the application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence.

In the embodiment, an access method running on the above-mentioned home gateway is provided as shown in FIG. 1, including the user equipment sending an access message to the home gateway. The access message includes a first source IP address, a first source MAC address, and a first source MAC address. A destination IP address and a first destination MAC address. When the first destination IP address is the IP address of the home gateway, the home gateway modifies the destination MAC address to the MAC address corresponding to the home gateway; the home gateway constructs a response message, and sends the response message to all Mentioned user equipment.

Example 1

The embodiment provides an access method running on the above-mentioned home gateway. FIG. 1 is a flowchart of an access process according to an embodiment of the present application. As shown in FIG. 1, the process includes the following steps.

In S101, the user equipment sends an access message to the home gateway, where the access message includes a first source IP address, a first destination IP address, and a first destination MAC address.

In the bridge mode of the home gateway, the user equipment obtains the public network address (for example: 10.20.30.x), and its gateway is the upper device of the home gateway, which is not in the same network segment as the home gateway address. The home gateway user device initiates a pairing For access to the home gateway IP address (for example: 192.168.1.1), the message will be directly forwarded to the external network and cannot be sent to the home gateway for processing.

The home gateway driver module completes the initial configuration shown in Figure 3 when it is powered on.

(1) Generate package rules and configure them to the driver module. The driver module generates internal rules and sends the access message with the destination IP address to the home gateway address to the protocol stack, otherwise the driver will directly forward it according to the chip hardware.

(2) Generate packet transformation rules, configure them to the protocol stack interception processing module, and the interception processing module generates access message matching conditions and transformation content.

(3) Dynamically configure the routing module, construct a routing rule from the source IP address to the user side according to the content of the message analyzed by the packet interception module, and configure the routing to generate routing entries.

The special processing before forwarding by the home gateway is added. The message sent by the home gateway user equipment reaches the home gateway and first receives the packet through the driver module.

S102: When the first destination IP address is the IP address of the home gateway, the home gateway modifies the destination MAC address to the MAC address corresponding to the home gateway; in some embodiments, the driver module finds that the packet is received The first destination IP of the access message is the IP address of the home gateway (for example: 192.168.1.1), it is not directly forwarded by hardware, but is sent to the protocol stack for processing.

The packet interception module of the home gateway protocol stack parses the access message, determines if the destination address is the home gateway address, and sends it to the address conversion module. Address conversion modifies the first destination MAC address of the access message to the MAC address corresponding to the home gateway, and records the first source MAC address. The message is sent from the layer 2 protocol stack to the home gateway itself for processing, and enters the layer 3 protocol stack for processing .

According to the packet content parsed by the packet interception module, construct a routing rule from the first source IP address to the user-side device, configure the route to generate a routing entry, for example, when the first source IP address is 192.168.1.x, configure a route 192.168.1.0/24 points to the route of br0.

As shown in Figure 2, the method also includes the following steps.

S103 The home gateway constructs a response message and sends the response message to the user equipment; in some embodiments, as shown in FIG. 4, this step includes that the home gateway is configured in the three-layer protocol stack according to the first destination IP address. Send it to the corresponding service module for processing. The home gateway processes this message, constructs a response message and returns it.

According to the route configured in S102, the home gateway performs route processing after finding this route, and the response message is forwarded to the LAN-side user equipment.

The address conversion module modifies the second source MAC address of the response message to the first destination MAC address in the original access message sent by the user equipment, that is, the source MAC address recorded in step S201.

After receiving the response message, the user equipment on the LAN side causes the access to continue, initiates subsequent interactive messages, and realizes the access of the user equipment on the LAN side to the home gateway.

As shown in Figure 5, taking the TCP access initiated by HTTP as an example, the processing flow of the TCP message interaction message of the user equipment accessing the home gateway of this application: First, the user equipment performs the TCP handshake access message (SYN message) for accessing the home gateway. ), the driver hardware interrupts the receipt of this message, puts this message on the protocol stack, the protocol stack analyzes the content of the message, and judges whether the destination IP address carried in the TCP message is the home gateway address, if it is the MAC address of the home gateway , Modify the destination MAC of the access message to the MAC address of the home gateway.

The protocol stack data packet processing function determines that the destination MAC address of the message is the home gateway's own MAC address, enters the IP layer for processing, and the home gateway generates a response message (SYN ACK message) according to business access.

The message is processed by the routing module, the routing entry is found, and the message is sent to the user access device on the LAN side.

The user equipment continues to perform the third packet (ACK packet) of the TCP handshake to access the home gateway, and also modifies the destination MAC through the home gateway to complete the TCP handshake and establish a connection.

The subsequent interactive messages such as the processing of the TCP GET message and the data message perform the same actions as the above process, which completes the entire access process of the user equipment to the home gateway.

Example 2

This embodiment provides an access method running on the above-mentioned home gateway. When the above-mentioned home gateway works in the bridge mode, FIG. 7 is a flow chart of the access process according to an embodiment of the present application. As shown in FIG. 7, the flow is Including the following steps.

S201 The user equipment sends an access message to the home gateway, where the youth access message includes a first source IP address, a first source MAC address, a first destination IP address, and a first destination MAC address.

In some embodiments, when the home gateway is in the bridge mode, the user equipment initiates access to the home gateway address, and the message is directly forwarded to the external network and cannot be sent to the home gateway for processing. The home gateway completes the configuration shown in Figure 6 when it is powered on.

(2) Generate packet transformation rules and configure them to the protocol stack interception processing module. The interception processing module generates access message matching conditions and transformation content, transforms the first destination MAC and first IP address of the access message, and returns the response The packets on the LAN side undergo a destination address conversion.

The access message sent by the home gateway user equipment includes the source IP address, the source MAC address, the destination IP address and the destination MAC address, and the packet is first received by the driver module when it reaches the home gateway.

One example is that the first source IP carried in the access message sent by the user equipment is: 10.46.xx, which is the public IP address obtained by the user, to access 192.168.1.1, which is the first address in the access message Destination IP address.

S202: When the first destination IP address in the access message sent by the user equipment to the home gateway is the home gateway IP address, modify the first destination MAC address to the MAC address corresponding to the home gateway; The driver module finds that the first destination IP of the message is the IP address of the home gateway (for example: 192.168.1.1), and sends it to the protocol stack for processing.

The protocol stack parses the access message, determines if the destination address is the home gateway address, records the first source MAC address of the access message, and modifies the first destination MAC address of the access message to the MAC address corresponding to the home gateway At the same time, the first source IP address is transformed into the IP address of the private network segment of the home gateway, and the first source IP of this access request is transformed into the IP address of the private network segment of the home gateway, such as: 192.168.1.3, so It becomes: 192.168.1.3 access 192.168.1.1.

The message is referred to the home gateway for processing in the second layer protocol stack, and enters the third layer protocol stack for processing. In the three-layer protocol stack, the first destination IP address is sent to the local processing flow, and the local service module constructs a response message and returns it.

S203 The home gateway constructs a response message and sends the response message to the user equipment; the home gateway transforms the response message in the address change module, and combines the transformation rules to transform the second source MAC address in the response message It is converted into the first destination MAC address of the access message sent by the user equipment, and the destination IP address in the response message is converted into the first source IP address carried in the access message sent by the user equipment, such as 10.46.xx, this The IP address is the address of the LAN-side device, and the LAN-side device can receive and process this message.

After receiving the response message, the user equipment on the LAN side can continue to initiate subsequent interaction messages to realize the access of the user equipment on the LAN side to the home gateway.

As shown in Figure 8, taking the user accessing the home gateway HTTP service to initiate TCP access as an example, the user equipment accesses the home gateway TCP message interaction message processing: first, the user equipment performs the TCP handshake access message (SYN message) for accessing the home gateway The driver hardware interrupts the received message, extracts the message and sends it to the protocol stack. The protocol stack analyzes the content of the message and judges that the destination IP address of the TCP message is the address of the home gateway. The destination MAC of the message is modified to the MAC address of the home gateway, and the source IP address of the message is converted to the IP address of the private network segment of the home gateway.

Continue through the protocol stack data packet processing, determine that the destination MAC address of the packet is the home gateway's own MAC address, enter the IP layer for processing, the corresponding service module processes the service access, and the home gateway generates a corresponding response packet (SYN ACK packet).

After the message passes through the address conversion module, the destination IP address of the response message is changed to the source IP address used by the LAN side device when it comes up according to the rules, and the message is sent to the LAN side user device.

The user equipment continues with the third packet (ACK packet) of the TCP handshake to access the home gateway, and also completes the TCP handshake and establishes the connection after the home gateway modifies the destination MAC and special firewall rules to modify the IP address.

Through the above steps, the problem that the home gateway works in bridge mode, the user accesses the device to obtain the public network address, and the private network address of the home gateway is on a different network segment, and the user cannot access the home gateway. Access to the home gateway from the user equipment on the LAN side.
