Abstract:
Described embodiments provide systems and methods for tunneling data packets to a server. A computing device can include a processor and a network interface. The processor is configured to execute a network service, a local application, and a virtual private network (VPN) application. The network service can receive a packet from the local application for transmission via a VPN tunnel, the packet comprising a source address of the computing device and a source port associated with the local application. The network service can determine that the packet matches a first tunnel filter. The network service can encapsulate, responsive to the determination that the packet matches the first tunnel filter, the packet with the header comprising a localhost destination address and a destination port associated with the VPN application. The network service can provide the encapsulated packet to the VPN application.
