US 2019/0173839 A1 · Local Interception Of Traffic To A Remote Forward Proxy

Abstract

An application using a VPN is programmed to transmit proxy traffic to a remote proxy server. Traffic to the proxy server is intercepted, shifted to user space, and processed according to one or more options. Traffic may be terminated by a local proxy that resolves domain names in traffic and requests referenced content. Intercepted traffic may include plain text data in headers that is encrypted before forwarding to a different proxy server. Traffic may be evaluated, such as a User Agent string in order to determine routing choices, such as blocking, throttling, local termination, transmitting through a VPN, or other options. Multiple VPNs may operate on the same user computer and proxy traffic may be intercepted and processed by transmitting it through a VPN, bypassing all VPNs, or routing through a different VPN.

Claims21

Dependent claims

A system comprising one or more processing units and one or more memory units operably coupled to the one or more processing units, the one or more memory units storing executable code effective to cause the one or more processing units to:

receive settings for a first Virtual Private Network (VPN) service and a second VPN service, settings for the first VPN service including a proxy setting comprising a first network identifier;
activate the first VPN service and the second VPN service, the first VPN service being associated with a first Virtual Network Device (VND) and the second VPN service being associated with a second VND;
establish a first tunnel between the second VPN service and a first VPN server;
route network traffic associated with the first network identifier to the first VND;
and
route at least some network traffic not associated with the first network identifier to the second VND.

3 more elements

A method comprising:

specifying, on a user's computer, settings for a first Virtual Private Network (VPN) service and a second VPN service, settings for the first VPN service on the user's computer including a proxy setting comprising a first network identifier;
activating, on the user's computer, the first VPN service and the second VPN service, the first VPN service being associated with a first Virtual Network Device (VND) and the second VPN service being associated with a second VND, the second VPN service establishing a first tunnel between itself and a first VPN server;
routing, by the user's computer, network traffic associated with the first network identifier to the first VND;
routing, by the user's computer, at least some network traffic not associated with the first network identifier to the second VND;
intercepting, by the user's computer, from the first VND, a first request to the first network identifier, the first request containing a first domain name;
terminating, by the user's computer, the first request by a local proxy server executing on the user's computer without sending the first request to a destination associated with the first network identifier;
and
issuing, by the user's computer, a redirected request to a destination associated with the first domain name, the redirected request being routed to the first VPN server through the first tunnel established by the second VPN service.
