Abstract
Transparently identifying users using a shared VPN tunnel uses an innovative method to detect a user of a shared VPN tunnel, after authenticating the user, using an assigned userid (that may be a virtual IP). The virtual IP is used as a cookie in each request made by the user. This cookie is an authentication token used by the gateway to detect the user behind a specific request for an Internet resource (such as an http/s request). The cookie is stripped by the gateway so the cookie is not sent to the resource.
