摘要： The present invention is related to a method for establishing via an appliance a transport layer protocol connection initiated by a server on a first network to a client connected from a second network to the first network via a secure socket layer virtual private network (SSL VPN) connection. The method includes the step of receiving, by an appliance, a transport layer connection request from a server on a first network to connect to a client connected to the first network via a SSL VPN connection from a second network. The transport layer connection request identifies a client destination internet protocol address and a client destination port on the first network. The method includes establishing, by the appliance, a first transport layer connection to the server on the first network, determining, by the appliance, the client on the second network associated with the client destination internet protocol address on the first network, and transmitting, by the appliance, connection information identifying the client destination port to an agent on the client. The agent establishes a second transport layer connection to the client destination port using a local internet protocol address of the client on the second network and establishes a third transport layer connection to the appliance, which it associates with the second transport layer connection.

摘要： The intranet IP address management solution of the appliance and/or client described herein provides an environment for efficiently assigning, managing and querying virtual private network addresses, referred to as intranet IP (IIP) addresses of virtual private network users, such as a multitude of SSL VPN users on an enterprise network. The appliance provides techniques and policies for assigning previously assigned virtual private network addresses of a user to subsequent sessions of the user as the user logs in multiple times or roams between access points. This technique is referred to IIP stickiness as the appliance attempts to provide the same IIP address to a roaming VPN user. The appliance also provides a configurable user domain naming policy so that one can ping or query the virtual private network address of a user by an easily referenceable host name identifying the user. The appliance and/or client agent also provide techniques to allow applications to seamlessly and transparently communicate on the virtual private network using the virtual private network address of the user or client on the private network.
摘要翻译：本文描述的设备和/或客户端的Intranet IP地址管理解决方案提供了一种用于有效地分配，管理和查询虚拟专用网地址的环境，被称为虚拟专用网络用户的内部网IP（IIP）地址，诸如大量企业网络上的SSL VPN用户。该设备提供用于在用户多次登录或者在接入点之间漫游时将用户先前分配的虚拟专用网地址分配给用户的后续会话的技术和策略。该技术被称为IIP粘性，因为设备试图向漫游VPN用户提供相同的IIP地址。该设备还提供可配置的用户域命名策略，以便可以通过标识用户的易于引用的主机名来ping或查询用户的虚拟专用网络地址。设备和/或客户端代理还提供技术，以允许应用程序使用专用网络上的用户或客户端的虚拟专用网地址在虚拟专用网络上无缝和透明地通信。

摘要： Systems and methods are described for using a client agent to manage HTTP authentication cookies. One method includes intercepting, by a client agent executing on a client, a connection request from the client; establishing, by the client agent, a transport layer virtual private network connection with a network appliance; transmitting, by the client agent via the established connection, an HTTP request comprising an authentication cookie; and transmitting, by the client agent via the connection, the connection request. A second method includes intercepting, by a client agent executing on a client, an HTTP communication comprising a cookie from an appliance on a virtual private network to the client; removing, by the client agent, the cookie from the HTTP communication; storing, by the client agent, the received cookie; transmitting, by the client agent, the modified HTTP communication to an application executing on the client; intercepting, by the client agent, an HTTP request from the client; inserting, by the client agent in the HTTP request, the received cookie; and transmitting the modified HTTP request to the appliance. Corresponding systems are also described.

摘要： A method for intercepting communication of a client to a destination on a virtual private network includes an agent executing on the client that intercepts a network communication of the client. The agent provides a virtual private network connection from a first network to a second network. The decision to intercept is based on a network destination description or an identification of an application authorized to be accessed via the virtual private network. In one case, the agent determines that a destination specified by the intercepted communication corresponds to a network identifier and a port of a network destination description of an application on the second network authorized for access via the virtual private network. In response to this determination, the agent transmits the intercepted communication.
