Port Mapping

## Overview

The Port Mapping feature resolves mismatches between internal and external UDP ports used for streaming. For example, if the internal network uses port `30011` but the external (WAN) mapping is port `20011`, you need to configure port mapping rules so the system routes traffic correctly.

> **Note:**
> - Only **external network UDP port** configuration is currently supported.
> - Each mapping rule supports exactly **one UDP port**. Port ranges cannot be added as a single rule.

## Setup Steps

### Step 1: Set the UDP Port on the Rendering Service

In the rendering service manager, configure the UDP port range. For a single port, use the format `30011-30011`. For multiple ports, specify a range such as `30011-30020`.

### Step 2: Configure Internal/External Port Mapping

Set up the streaming port mapping rules in the management panel:

- In the **Internal Network Port** field, enter the UDP port configured in Step 1.
- In the **External Network Port** field, enter the corresponding external (WAN) port number.
- If a port range was used in Step 1, create separate mapping rules for each port in the range.

### Step 3: Open Ports on the Router

Ensure the configured streaming ports are accessible by opening them through your router or firewall settings.
