Abstract

A method for redirecting specific network traffic intended for a target device on a first data network is described. The method inserts a redirector into a first network in front of a target device and intercepting a transmission from the target device. The method then configures the network characteristics of the redirector to use the network addresses of the target device. Once configured the redirector inspects the network traffic on the first network to identify specific services, and sends the network traffic associated with the specific service to a destination device on a second network.

Claims (16)

1. A method for redirecting specific network traffic between a first data network and a target device, the method comprising:

inserting a redirector into the first network, the first network comprising an Ethernet network, in front of the target device by inserting a network cable for the target device into a first network interface on the redirector and connecting the target device to second network interface on the redirector, wherein the redirector is also connected by a third network interface to a second data network;

setting an initial network address of the redirector device to all zeros;

intercepting, at the redirector, an initial transmission from the target device, thereby allowing the redirector to determine the network addresses of the target device;

configuring the redirector to use the network addresses of the target device in place of the initial network address and to use the network address of the target device at a port of the redirector connected to the target device with a Locally-Administered Address bit set to on;

inspecting the network traffic on the first network to identify a specific type of network traffic according to a higher level protocol in the network traffic; and

sending, using the redirector, the network traffic associated with the specific type of network traffic to the second network.

2. The method of claim 1 wherein the network traffic is also sent to an original destination on the first network.

3. A method for redirecting specific network traffic between a first data network and a target device, the method comprising:

inserting a redirector into the first network in front of the target device by inserting a network cable for the target device into a first network interface on the redirector and connecting the target device to second network interface on the redirector, wherein the redirector is also connected by a third network interface to a second data network;

setting an initial network address of the redirector device to all zeros;

intercepting, at the redirector, an initial transmission from the target device, thereby allowing the redirector to determine the network addresses of the target device;

configuring the redirector to use the network addresses of the target device in place of the initial network address and to use the network address of the target device at a port of the redirector connected to the target device with a Locally-Administered Address bit set to on;

inspecting the network traffic on the first network to identify a specific type of network traffic according to a higher level protocol in the network traffic; and

sending, using the redirector, the network traffic associated with the specific type of network traffic to the second network, the second network comprising a cellular network.

4. The method of claim 3 wherein the network traffic is also sent to an original destination on the first network.
