The principle behind the operation of an IP proxy server firewall is mainly by acting as an intermediary in the conversation layer of the open-system interconnection digital model, serving to protect network security.

It establishes a connection with network servers to provide internet clients with secure access to network information while safeguarding client privacy and preventing network attacks.

 

Generally, internet connections are established directly between two intelligent terminals—an internet-enabled device (often a mobile client) and a network server. However, a proxy network server acts as an intermediary between these two. Mobile clients connect to proxy servers, which then communicate indirectly with network servers, establishing a virtual private secure channel on the internet, ensuring the security of users' personal privacy and effectively preventing various network attacks.

 

Specifically, the process of proxy browsing is as follows:

firstly, the mobile client connects to the proxy server, which then establishes a connection with the target network server or retrieves the required resources. Sometimes, the target network server may have a large computer disk cache area, allowing the proxy server to retrieve resources directly from the cache without sending requests to the target server, thereby speeding up the internet connection.

In some cases, the proxy server may also modify the original requests from the mobile client and the original responses from the target server to meet specific requirements.

Conclusion

In summary, an IP proxy server firewall ensures the security and privacy of internet connections by acting as an intermediary, providing users with a secure and efficient network access experience.
