First Claim
Patent Images
1. A method of configuring a device couple to a network gateway, comprising:
- upon the device being assigned a Wide Area Network (WAN) Internet Protocol (IP) address by the gateway device, the device iteratively;
determining whether a LAN IP address of the device conflicts with the assigned WAN IP address by determining whether the LAN IP address of the device is on a same subnet as the WAN IP address assigned to device;
determining whether the assigned WAN IP address is within a predetermined secondary LAN IP address range;
changing the LAN IP address of the device to a different subnet if the assigned WAN IP address is within the predetermined secondary address range; and
changing the LAN IP address of the device to a host number within the predetermined secondary IP range if the assigned WAN IP address is not within the predetermined secondary LAN IP address range.

Abstract
A device comprising a router may be configured to couple to a gateway device and may be configured, upon being assigned a Wide Area Network (WAN) Internet Protocol (IP) address by the gateway device, to iteratively: (1) determine whether a LAN IP address of the device conflicts with the assigned WAN IP address; and (2) change the LAN IP address of the device if the LAN IP address of the device conflicts with the WAN IP address assigned by the network gateway.
