TrayProxy is a Windows system proxy forward tool and a lightweight utility that allows you to set up, configure, and use forwarding proxies.
If you are looking for a fast way to pass requests from isolated private networks through the Internet through firewalls, the best choice is a forwarding agent. In addition to allowing you to better control traffic, the forwarding agent can also act as a mask because it runs directly in the traffic flow.

TrayProxy is portable, so just download, unzip and start it. The first time you start, the application creates multiple configuration files in the same location in the application folder.
The application also supports XrayCore, which allows you to use SS, VMESS, or VLESS protocols, and allows streaming using TCP, GRPC, or WS. The disadvantage is that the developer mentioned that the tool only supports HTTP forwarding.
The forwarding agent is the intermediary between the user equipment and the Internet. Typically, client requests are validated and sent directly to the web server. Instead, the forwarding proxy server evaluates the request and routes it to the intended destination on behalf of the client. TrayProxy is designed to simplify the setting, configuration and use of forwarding proxy. It can be completely customized according to your needs.
For those who need to access restricted data due to various factors, TrayProxy will be an asset.
