VPN Gateway Automatic IP Configuration via Packet Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home network systems in apartment buildings face challenges in network separation, particularly with logical network separation, as they require replacing existing servers and wall pads, and changing settings, which is costly and inconvenient, and do not allow for easy identification of problematic VPN gateways or home network devices.
Innovation Solution
A method and system for automatically configuring an IP to a VPN gateway using a local packet analyzer and network setting unit, allowing the VPN gateway to share IP portions with home network devices, enabling easy identification of issues and reducing installation costs by not requiring manual setting changes or equipment replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If logical network separation is implemented using VPN, then network security is improved, but device complexity and installation cost increase due to requiring replacement of existing servers and wall pads
Solution Approach 1:
The VPN gateway performs self-configuration by automatically acquiring the IP address of the home network device through packet analysis and setting its own IP based on the acquired address. This eliminates the need for manual configuration and reduces the complexity of system deployment, allowing network separation to be implemented without replacing existing servers and wall pads.
Solution Approach 2:
The VPN gateway acts as an intermediary device between the home network device and the VPN server. It automatically obtains network configuration information from the home network device and uses it to establish the VPN connection, thereby simplifying the overall system architecture and avoiding the need for complex manual setup procedures.
2Manufacturing precision
If manual IP configuration is performed for VPN gateway, then configuration precision is improved, but installation time and labor cost increase
Solution Approach 1:
The VPN gateway automatically acquires the IP address of the home network device through packet analysis and configures its own IP address based on the acquired information. This self-configuration mechanism ensures accurate IP assignment without requiring manual intervention, thereby reducing installation time while maintaining configuration precision.
Solution Approach 2:
The VPN gateway performs preliminary packet analysis to acquire the home network device's IP address before completing its own configuration. This preliminary action ensures that the IP configuration is based on accurate, pre-obtained information, eliminating the need for manual configuration while maintaining precision.
3Ease of operation
If existing management system is used for VPN gateway management, then ease of operation is improved, but system compatibility deteriorates due to VPN gateway requirements
Solution Approach 1:
The VPN gateway is designed to work with existing management systems by using standard network protocols and automatic configuration mechanisms. It can be managed through the existing wall pad and server infrastructure, making the management system universal and compatible with both traditional and VPN-based network devices without requiring separate specialized management tools.

AI summary
A method of automatically configurating an IP of a VPN gateway in a home network system applied to an apartment building composed of a plurality of unit spaces includes: providing a home server connected to a network, a plurality of home network devices installed for unit spaces, respectively, a VPN server installed between the home server and the home network devices, and VPN gateways individually installed for the home network devices between the home network devices and the VPN server; acquiring an IP of an individually corresponding home network device using a local packet analyzer of the VPN gateway; and creating an IP of the VPN gateway using a network setting unit of the VPN gateway, wherein the network setting unit may make a portion of the IP of the VPN gateway be the same by referring to a portion of the IP of the individually corresponding home network device.
