## Overview

This configuration panel allows you to register a custom EDNS identifier and map it directly to a specific security profile, enabling granular filtering for distinct network segments.

## Interface Overview

Use this modal to define your routing parameters and register a new identifier to your active list.

| **Interface Element** | **Focus & Description**                                                                                                                 |
| --------------------- | --------------------------------------------------------------------------------------------------------------------------------------- |
| **Tag**               | Enter your unique 4-digit EDNS0 tag in this text field. This exact string must be injected into the DNS payload by your local hardware. |
| **Note**              | An optional text field to add internal descriptions or labels to easily identify the network segment.                                   |
| **Add**               | Click this blue button to save the new tag and add it to your active list.                                                              |

:::hint{type="warning"}
You can assign a specific EDNS tag to one security policy, but a single policy cannot be linked to multiple EDNS tags simultaneously.
