    摘要： Systems and methods are described for using a client agent executing on a client to send ICMP messages to an appliance connected via a virtual private network Methods include: establishing, via a client agent executing on a client, a transport layer virtual private network connection with an appliance; intercepting, by the client agent at the network layer, an ICMP request originating from the client; and transmitting, by the client agent via a transport layer connection, the ICMP request to the appliance. Addition methods describe determining, by the appliance, the address identified by the ICMP request corresponds to a second client, the second client also connected via a virtual private network to the remote machine; and transmitting, by the appliance to the second client via the virtual private network connection, the ICMP request. Corresponding systems are also described.

    摘要： A method for allowing or denying, by an appliance, access to a resource by an application on a client via a virtual private network connection includes basing the decision to allow or deny access on identification of the application. The appliance intercepts a request from an application on a client on a first network to access via a virtual private network connection a resource on a second network. The appliance identifies the application and associates with the intercepted request an authorization policy based on the identity of the application. The appliance determines, using the authorization policy and the identity of the application, to either allow or deny access by the application to the resource.

    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.

    摘要： An appliance and method for authorizing a level of access of a client to a virtual private network connection, based on a client-side attribute includes the step of establishing, by an appliance, a control connection with a client upon receiving a client request to establish a virtual private network connection with a network. The appliance transmits, via the control connection, a request to the client to evaluate at least one clause of a security string, the at least one clause including an expression associated with a client-side attribute. The client transmits, via the control connection, a response to the appliance comprising a result of evaluating the at least one clause by the client. The appliance assigns the client to an authorization group based on the result of evaluation of the at least one clause.
