After this network equipment receives the data packet that contains IP address, order ground that this computer 10 sent, then earlier judge whether this data packet is an address translation agreement (AddressResolution Protocol, ARP) inquiry package, and be not the adapting card address (MAC Address) (step S104) of inquiry network equipment itself.
When if this data packet is the inquiry package of this address translation agreement (ARP), then this network equipment can confirm whether default network gateway 20 addresses exist (step S106) in this computer 10, is 192.168.10.X as this computer 10 in default these network gateway 20 addresses of company, and this computer 10 moved in the family and when for the first time online, the network gateway address of this 192.168.10.X necessarily can't respond, that is does not exist.
At this moment, this network equipment can be given computer 10 (step S108) with adapting card address (MAC Address) passback of itself, allow this computer 10 data packet can be sent to the adapting card address (MAC Address) of this network equipment, make this network equipment become the network gateway (step S110) of this computer 10, be responsible for handling the data packet that this computer 10 is sent, become this computer 10 by this network equipment emulation again, the transmission and the exchange (step S112) of data packet are carried out in direct and this IP address, order ground.
Because each adapting card address (MAC Address) is unique in the network, as long as just can carry out online so the computer in the network is known the adapting card address (MACAddress) of this network gateway 20, therefore know the adapting card address (MAC Address) of this network equipment when this computer, can be directly carry out the transmission and the exchange of data packet according to this network adapting card address (MAC Address) and network equipment, so this computer 10 promptly can any IP configuration and the computer of IP address, arbitrary order ground carry out the transmission and the exchange of data packet.
Yet, if the received data packet of this network equipment is not the inquiry package (step S104) of this address translation agreement (ARP), then transmit data packet to this network gateway 20 according to default network gateway 20 addresses in this computer 10, transfer to this IP address, order ground (step S112) again through this network gateway 20, as in the network of company employed computer 10 be by this network gateway and outside Wide Area Network transmission data packet.
Again, if the received data packet of this network equipment is the inquiry package (step S104) of this address translation agreement (ARP), and also confirm that default network gateway 20 addresses are (the step S106) that exist in this computer 10, then transmit data packet to this network gateway 20 with default network gateway 20 addresses in this computer 10, transfer to this IP address, order ground (step S112) again through this network gateway 20, when the company that for example once more the computer that uses in the family moved to again is for the first time online.
And above-mentioned all be in the online all normal situation of all-network, when if this computer uses network equipment for the first time, when perhaps this network equipment can't connect network, the present invention has also designed the Auto-Sensing machine and has put, allowing user's setting network configuration again, is online detecting schematic flow sheet of the present invention as Fig. 3
Eds machine in network equipment of the present invention is put, in the time of at first can't transmitting or exchange this data packet (step S200) as if this computer 10, then this network equipment is sent an information to this computer 10, make display requirement user on the browser of this computer 10 check the on line state (step S202) of the network port of this network equipment, as shown in Figure 4.
This moment is after if the user checks that the network port connection of network equipment is errorless, when this computer 10 still can't transmit or exchange this data packet (step S204), this network equipment can be checked the on line state with local side, as the ISP dealer, and reconnect automatically, and the information of sending requires the user to wait for for a moment (step S206), as shown in Figure 5 to the browser of this computer.
If reconnect when still failing automatically, the information of then sending is to the browser of this computer, and demonstrating the user should seek to assist to the ISP dealer, as shown in Figure 6.
Or after reconnecting successfully automatically, still can't on-line network (step S208), then this network equipment can be checked number of the account under the PPPoE operator scheme and password whether wrong (step S210), when if PPPoE replys number of the account and password mistake, the information of then sending requires the user to re-enter number of the account, password (step S212), as shown in Figure 7 to the browser of this computer, and store number of the account and the password that the user inputed, to finish the purpose of automatically connect.
