--- title: "Configure for Air-Gapped Operation" sidebar_position: 3 description: Server settings that depend on internet access and should be disabled or adjusted for an air-gapped deployment. --- After successful deployment, you'll need to configure Mattermost for air-gapped operation. The following sections describe features that rely on internet access and offer recommendations for settings. ## Mobile push notifications Mattermost can use mobile push notifications to notify users of new messages and activity. These notifications require a server component to be deployed to send the notifications to mobile devices. By default, Mattermost uses the public push notification service, which isn't available in an air-gapped environment. We recommend disabling push notifications in **System Console > Environment > [Push Notification Server](/administration-guide/configure/environment-configuration-settings#push-notification-server)**. ## Email Unless you've set up an internal air-gapped email service, we recommend disabling email invitations and email verification from **System Console > Authentication > Signup**. ## Website link previews Website link previews require a connection to the internet to fetch the content of the links. We recommend [disabling website link previews](/administration-guide/configure/site-configuration-settings#enable-website-link-previews) in **System Console > Site Configuration > Posts**. ## GIF picker The GIF picker relies on a third-party service which has a dependency on external internet access. You can disable it in **System Console > Integrations > GIF**. ## Notices [In-product notices](/administration-guide/manage/in-product-notices) require internet access to periodically inform administrators and end users of new product improvements, features, and releases. You can disable notices in **System Console > Site Configuration > Notices**. ## Telemetry To avoid log errors, we recommend disabling [telemetry-related features](/administration-guide/manage/telemetry), including the security update check, and error and diagnostics reporting features.
