What is the operation of Single Gateway (Restricted) Mode?

Single Gateway (Restricted) Mode operates by requiring that inbound requests must match a defined IP in the External Gateway IP field. This configuration ensures that only specific, authorized IP addresses are allowed to initiate connections, enhancing the security of the system. The purpose of this mode is to limit access to the secure resources only to predetermined IPs, ensuring that unauthorized users do not have the ability to connect through the gateway.

In this mode, clients trying to connect will be checked against the list of defined IP addresses, allowing for a more controlled access approach. This feature is particularly useful in scenarios where organizations need tighter security measures and cannot afford to have unrestricted access to sensitive resources.

This functionality is critical as it establishes a core mechanism for managing which clients can contact the gateway, thus preventing unauthorized access and potential breaches.
