Abstract: A request is received from a user device to establish a VPN tunnel. The VPN tunnel is established with a first private IP address of the VPN concentrator and a second private IP address of the user device as endpoints. An outbound packet for transmission to a target is received from the user device. A third private IP address associated with the tunnel is looked up based on a VPN session. A substitution of the first private IP address with the third private IP address in a header of the outbound packet is performed. NAT is performed on the outbound packet to replace the third private IP address with a third public IP address of the VPN concentrator. The outbound packet is then transmitted to the target.

Abstract: A method including monitoring, by a first device in communication with a second device in a mesh network, a triggering event associated with optimizing a meshnet connection utilized by the first device and the second device to communicate meshnet data; comparing, by the first device based at least in part on determining an occurrence of the triggering event, a threshold value with a measured value associated with a communication condition associated with communicating the meshnet data via the meshnet connection; and transmitting, by the first device to the second device based at least in part on a result of the comparing, coordination information including identification information that identifies an optimal midpath node and timing information that indicates a connection time associated with connecting with the optimal midpath node for optimizing the meshnet connection. Various other aspects are contemplated.

Abstract: Systems and methods for effectively managing security and privacy measures during a user's connectivity session with a VPN service are provided. The systems and methods use a computer program that introduces a double-NAT feature at the network layer and a temporary hash table containing the minimally necessary temporary data to link two NAT sessions together in a secure manner. The systems and methods avoid including the dynamic management of IP addresses or requiring each client to have an IP address assigned beforehand to avoid compromising the user's identity by hard linking the session traces with the client.
