ROUTER AND METHOD FOR CONFIGURING IP ADDRESSES OF THE ROUTER
First Claim
1. A router, comprising:
- an internet protocol (IP) address searching module operable to broadcast a dynamic host configuration protocol (DHCP) discover packet over a network so as to search a private IP address of a modem connected with the router;
a packet receiving module operable to receive a DHCP offer packet from the modem, wherein the DHCP offer packet comprises the private IP address of the modem;
an IP address obtaining module operable to obtain the private IP address of the modem from the DHCP offer packet;
an IP address configuration module operable to configure IP addresses of a wide area network (WAN) port and a local area network (LAN) port of the router according to the private IP address of the modem, so as to allow the private IP address of the modem to be in the same network segment with the IP address of the WAN port but in different network segments with the IP address of the LAN port; and
a processor that executes the IP address searching module, the packet receiving module, the IP address obtaining module, and the IP address configuration module.

Abstract
A method for configuring IP addresses of a router broadcasts a dynamic host configuration protocol (DHCP) discover packet over a network for receiving a DHCP offer packet sent from the modem. The DHCP offer packet comprises the private IP address of the modem. The method further obtains the private IP address of the modem from the DHCP offer packet, and configures IP addresses of a WAN port and a LAN port of the router according to the private IP address of the modem, so as to allow the private IP address of the modem to be in the same network segment with the IP address of the WAN port but in different network segments with the IP address of the LAN port.
