Abstract: PURPOSE: A method for linking a private network and a public network using a network address conversion table and a recording media therefor are provided to achieve an efficient inter-working of a private network and a public network using a network address conversion table. CONSTITUTION: A gateway receives a packet transmitted to a public network node from a private network node(40). The gateway, based on information comprised in the packet header of the received packet, searches a conversion table through the first hash table and finds out a matching entry(41). In case that the matching entry doesn't exist(42), the gateway generates a new conversion table entry(43). The gateway, according to the new conversion table entry, reconfigures the packet header of the private network packet after replacing the private origination address and port with an authorized IP address and port(44) and transmits the packet comprising the authorized address to the public network(45). If a response packet is received from the public network(46), the gateway, referring to information comprised in the packet header of the received packet, searches the conversion table through the second hash table and finds out a matching entry(47). Based on the matching entry, the gateway reconfigures the packet header of the response packet after replacing the authorized destination address and port with the private network address and port(48) and transmits the packet comprising the private address to the private network(49).
