# Port Configuration

The **Port Configuration** feature allows you to customize individual ports based on your specific requirements. Once you define specific criteria for a port, it will prioritize using proxies that match those settings. This provides greater control over your connections and enhances efficiency.

## 1. Key Benefits Of Port Configuration

* Greater control over proxy selection based on location and ISP.
* Optimized performance by ensuring ports always use preferred proxies.
* Enhanced automation with customizable auto-refresh and rotation settings.
