Configures the SSH proxy's callback client feature, which allows devices behind NAT to initiate a reverse tunnel back to the proxy server. This enables the proxy to route incoming connections to otherwise unreachable devices.

General Settings

Callback Identifier: The username used by callback clients when authenticating to the proxy server. Only alphanumeric characters are allowed. Default is CallbackClient. Change this if you need to use a different service account name.

Notifications

Notification Emails: Email addresses that receive alerts when a callback client connects or disconnects unexpectedly. Add one email address per entry.

Callback clients run as persistent background services on managed devices. When a device establishes a callback tunnel, the proxy server can route SSH connections to it without requiring the device to have a public IP address.
