摘要： Methods and systems for transmitting data packets from a host to a destination via a virtual private network (VPN) connection at a VPN gateway. VPN gateway receives encapsulated packets via the VPN connection. The encapsulated packets encapsulate the data packets originated from the host. VPN gateway decapsulates the encapsulated packets to retrieve the data packets. VPN gateway determines whether the data packets originated from an IoT device based on IP address of the host. When the host is the IoT device, VPN gateway performs deep packet inspection (DPI) on the data packets. VPN gateway determines whether the data packets are allowed to be transmitted to the destination. When the data packets are allowed to be transmitted to the destination, VPN gateway transmits the data packets to the destination.
