Abstract: The present solution provides systems and methods for supporting network communication, including UDP network communication, between clients and servers at data centers, over a cloud VPN. An agent can receive a user datagram protocol (UDP) packet. The agent can generate a header for the UDP packet identifying a destination server at a data center of a plurality of data centers. The agent can establish a channel to a virtual private network (VPN) server of a cloud-based VPN as a service. The agent can encapsulate the UDP packet using the header and transmit, via the channel, the encapsulated UDP packet to the VPN server, the encapsulated UDP packet configured to identify the data center according to a table of the VPN server and content of the header.

Abstract: A method may include, at a computing device, receiving a token from an appliance operating as a gateway between a client computing device and the computing device, the token being generated based upon a key of the computing device, and establishing a first connection with the appliance based upon the token, with the first connection being persistent. The method may further include, at the computing device, receiving a request from the appliance via the first connection, the request being for a remote session, and responsive to receipt of the request, establishing a second connection with the appliance that enables the client computing device to access the session.
