# Citrix virtual channel allowlist configuration

The Citrix platform requires specific DLLs and executables to be allowlisted to enable proper communication. The required virtual channel allowlist configuration depends on the version of Citrix Virtual Apps and Desktops in use.

The following sections detail which components must be explicitly allowed for each supported version.

## Versions lower than 2507

* **Policy name**: Virtual channel allow list
* **Status**: Disabled

{% hint style="info" %}
The policy must be created and assigned, but its value set to "Disabled". When the policy is not active, the DVC won’t work.
{% endhint %}

For detailed configuration information, see the [Citrix documentation](https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/2402-ltsr/hdx-transport/virtual-channel-allow-list).
