Abstract

A network device providing access to an external device by configuring the network device to control the flow of traffic from the external device to the network device. The flow control may include retrieving an IP address or port number from a bridged device and applying it to a stack stored in the memory of the network device so that the bridged device and network device share the same IP address.

Claims (13)

1. A network device, comprising:

an access point client having a DHCP client;

a processor in communication with the access point client, the processor being programmed using programming commands to:

analyze incoming traffic from an external device,

determine if a port address received by the access point client is a port address associated with the network device, and

if the received port address is the port address of the network device, directing content of a packet to a stack stored in a memory of the network device; and

wherein a local internet protocol (IP) address of the packet transmitted from the external device is replaced with an IP address of the access point client, and

wherein the access point client directly shares its IP address with the external device.

2. The network device of claim 1 , wherein the processor is programmed to determine if a link to the external device is up.

3. The network device of claim 2 , wherein if the processor determines that the link to the external device is up, the processor is programmed to stop the DHCP client of the access point client if the DHCP of the access point is running.

4. The network device of claim 3 , wherein the processor is further programmed to analyze packets of data received by the access point client to determine if an A.C.K. response from the external device is present in the received packets, and if an A.C.K. response from the external device is present in the received packets, the processor is programmed to retrieve selected settings from the received packets.

5. The network device of claim 4 , wherein the processor is programmed to apply at least one of the retrieved selected settings to a protocol stack stored in a memory of the network device.

6. The network device of claim 5 , wherein the at least one selected setting is an I.P. address of the external device.
