Remote Access Control Server for Home Network Port Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in remotely accessing devices within a home network due to private IP address information, making it complex for external devices to connect, especially when the home network is set up in a private environment.
Innovation Solution
A remote access control server is employed to request port forwarding for devices within the home network, updating access information to include public IP address and external port numbers, allowing remote access devices to connect from outside the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If port forwarding is manually set up for devices in a private home network, then remote access capability is improved, but device complexity and ease of operation deteriorate due to the complex configuration process
Solution Approach 1:
The patent introduces a remote access control server as an intermediary between the home network gateway and external devices. This server automatically manages port forwarding configurations, receiving requests from external devices and coordinating with the gateway to establish connections without requiring manual user configuration. The server acts as a mediator that simplifies the complex port forwarding process while maintaining remote access functionality.
Solution Approach 2:
The system enables self-service remote access by allowing external devices to automatically request and establish connections through the remote access control server. The gateway and server work together to automatically configure port forwarding rules based on device requests, eliminating the need for users to manually set up complex network configurations. The system serves itself by automatically managing the connection establishment process.
2Ease of operation
If automatic port forwarding is implemented through a remote access control server, then ease of operation is improved, but device complexity increases due to the additional server infrastructure
Solution Approach 1:
The remote access control server performs multiple functions: it acts as an intermediary for port forwarding requests, maintains a registry of devices in the home network, manages connection sessions, and coordinates with the gateway. By consolidating these multiple functions into a single server, the system reduces overall complexity compared to having separate specialized components for each function, while still providing automatic port forwarding capability.

AI summary
There is provided a method for allowing a remote access device to access a remote access target device within a home network. The method includes receiving, from a remote access agent of the home network, access information of the remote access target device within the home network and access information of the remote access agent; receiving a request for the access information of the remote access target device from the remote access device; requesting, to the remote access agent, port forwarding for the remote access target device based on the access information of the remote access target device and the remote access agent; receiving an answer to the request from the remote access agent, and updating the access information of the remote access target device based on the received answer; and sending the updated access information to the remote access device.
