Description: A gateway subnet is an essential component in the architecture of virtual networks. It is a specific subnet that houses the virtual network gateway, which acts as a connection point between a virtual network and other networks, whether on-premises or in the cloud. This subnet enables secure and efficient communication between different environments, facilitating the integration of services and resources. The gateway subnet is configured with specific IP addresses and must meet certain address space requirements to ensure its functionality. Additionally, it is important that this subnet does not contain other resources, such as virtual machines, to avoid routing conflicts and ensure optimal performance. Proper configuration of the gateway subnet is crucial for establishing VPN connections, ExpressRoute, and other connectivity solutions that allow organizations to extend their on-premises networks to the cloud. In summary, the gateway subnet is a key element that facilitates connectivity and communication between different networks, ensuring that cloud resources are accessible and interconnected effectively.
