Router, network system, and network setup method
First Claim
1. A router connected between a private network to which a terminal is connected and an external network, said router:
- receiving a transmission packet broadcast from said terminal, said transmission packet containing a MAC address; and
storing network information in which an IP address and Port No. are related to said MAC address, said IP address and Port No. being different from those of other terminal already setup.

Abstract
A router facilitate a network setup including a Port No., and a network system employs the router. The router receives a transmission packet containing a MAC address broadcast from a terminal in a network. The router then relates the IP address and Port No. to the MAC address and store them as network information. The IP address and Port No. are different from those of a terminal already setup. This network information is sent by designating the MAC address. When a transmission packet designating Port No. of the terminal is received from an external network, the router forwards the transmission packet to the terminal whose Port No. stored matches the designated Port No.

4. A router connected between a private network to which a terminal is connected and an external network, said router comprising:
-
a first controller for generating an IP address and Port No. on receiving a transmission packet broadcast from said terminal, said transmission packet containing a MAC address; and
a memory for storing said IP address and Port No. as network information related to said MAC address;
wherein said first controller generates said IP address and Port No. different from those of other terminal already stored in said memory. - View Dependent Claims (5, 6, 9)

10. A network system linked to an external network, said network system comprising:
-
a terminal which broadcasts a transmission packet containing its own MAC address to a connected network; and
a router which receives said transmission packet broadcast from said terminal, and stores an IP address and Port No. as network information related to said MAC address, said IP address and Port No. being different from those of a terminal already setup. - View Dependent Claims (11, 12, 13, 14, 15, 16)
