The apparatus includes a direct connection part for providing a direct connection in response to a connection request from the first network device, said request being a request to connect to a second network device in a second private network. Further, an address change part is provided for changing subnet numbers of origination and destination addresses of a packet transferred outside the first private network through the direct connection.
BACKGROUND This Application claims priority from Korean Patent Application No.2002-12219, the disclosure of which is incorporated herein by reference.
SUMMARY This disclosure teaches a network-connecting apparatus for a first private network having a first network device. The apparatus comprises a direct connection part for providing a direct connection in response to a connection request from the first network device, said request being a request to connect to a second network device in a second private network. Further, an address change part is provided for changing subnet numbers of origination and destination addresses of a packet transferred outside the first private network through the direct connection.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a structure of a network formed with network-connecting apparatuses according to an exemplary implementation of the disclosed teachings;
DETAILED DESCRIPTION Hereinafter, a network-connecting apparatus and method according to exemplary implementations of the disclosed teachings will be described in detail with reference to accompanying drawings. Like reference numerals indicate like constituents respectively in drawings.
The direct connection part 240 provides direct connections between the network devices 154 a to 154 n inside the private network 150 and the network devices 164 a to 164 n that are outside the private network 150 and form part of a second private network 160. The direct connection part 240 has an address acquisition part 242 and a connection management part 244. The address acquisition part 242 acquires a public IP address from the Domain Name Server 120. For example, 208.229.23.30, is a public IP address of the private network 160 to be connected. This could be based on a domain name of the network device 164 a, such as �lion.printer� that formed part of the network 160 that is waiting to be connected. This domain name is received from the network device 154 a that forms part of the private network 150. The connection management part 244 is connected to a gateway of the private network 160 (that is waiting to be connected), on a basis of the acquired IP address, to form a tunnel.
