Abstract

In one aspect, a computerized system useful for implementing a virtual private network (VPN) including an edge device that automatically establishes an Internet Protocol Security (IPsec) tunnel alongside an unsecure Multipath Protocol (MP) tunnel with a gateway device in preparation for a transmission of a secure traffic communication. The edge device has a list of local subnets. The edge device sends the list of local subnets to the gateway during an initial MP tunnel establishment handshake message exchange between the edge device and the gateway device. Each subnet includes an indication of whether the subnet is reachable over the VPN. A gateway device that automatically establishes the IPsec tunnel alongside the unsecure MP tunnel with the edge device. An enterprise datacenter server that comprises an orchestrator module that receives a toggle the VPN command and enables the VPN on the orchestrator. The orchestrator informs the edge device the list of subnets is accessible over the VPN causing the edge device to update the gateway device with a new list of subnets of the edge device that accessible over the VPN.
