After you've registered Gateway Connectors, you can specify a health check URL and restrict IP addresses for your connectors. If a health check URL is not specified, the DNS and HTTP information is not displayed in the health check status for a connector. For the Gateway Connectors, you do these actions:

Restricting source IP addresses provides additional security to make sure that only Gateway Connectors with the IP addresses you specify can connect to your private network. If you restrict source IP addresses, your Gateway Connectors should have a fixed IP address, either by setting a static IP address for the Gateway Connector when it is deployed in a vSphere environment or ESXi environment, or creating a DHCP IP reservation on your network.

Depending on the number of active Gateway users in your environment, a component of the Protect Backend that is responsible for managing incoming tunnels from the connector might scale the resources that are allocated to your organization. Each Gateway Connector establishes a tunnel to this component and has a health check performed on it. The health check status and Status columns indicate the state of those tunnels from the connector to the component that is responsible for managing them. For example, if the Health Check column status displays X/2, this means that two of the components are allocated to your organization at that time. If the column displays 2/2, the connector has successfully established two tunnels to the component. If you see 0/2 or 1/2 that means the connector has either not established a tunnel or has established 1 out of the 2 tunnels that are required. If the status is , some but not all of your users are able to access resources on your private network.

The health check URL can be any URL within your private networks that you want Gateway users to be able to connect to. Gateway periodically sends an HTTP or HTTPS GET request, including a DNS lookup, through each Gateway Connector tunnel to this URL. The Health check status expands to display Tunnel, DNS, and HTTP connection status for each connector. A status of 2/2 indicates that everything is working correctly. A status of 0/0 indicates that the status check of a new connection is still pending.

The Status column displays the enrollment status of the Gateway Connector with the Protect Backend. The indicates that the Gateway Connector has successfully completed the enrollment process and has established a connection to the Protect Backend. The status column displays the connection state and might include a security message (for example, if the connector requires a restart to apply an update).
