# DMZ Gateways
In the **Setup** → **DMZ Gateways** section you can add, modify or delete a DMZ gateway.
DMZ Gateways can be filtered in the **Filters** panel on the right of the page. Entries can be filtered by **Name, Internal port, Internal address**, and **External address**.
Learn how to use the **toolbar** at the top of the page [here](/data-mover-1.21/getting-started/navigate-through-primeur-data-mover.md#the-toolbar).
Select the  3-dot icon at the end of each result to Edit or Delete the DMZ Gateway.
To create a new DMZ Gateway, click **Setup** → **DMZ Gateways** → **New** and complete these properties:
* Name
{% hint style="danger" %}
The **Name** field can only contain alphanumeric characters.\
The minus '-' and underscore '\_' characters are accepted, as long as they are NOT at the beginning/end of the Name. For example:
* DMZ\_Gateway is accepted
* \_DMZGateway is not accepted
Other special characters are not accepted, e.g. no hash #, asterisk \*, percent %, dollar sign $, ampersand &, pipe | and so on.
{% endhint %}
* Description
* Internal Address
* External Address
* Internal Port
