Abstract:
1. A network system comprising a first image processing apparatus connected to a first network and a second image processing apparatus connected to a second network having a network address different from that of the first network, wherein the first image processing apparatus includes: a first network device connected to the first network; a second network device that builds a third network, that is different from the first and second networks, between the first image processing apparatus and a terminal that is connected to the second network, and in the terminal a first IP address in the second network is set; an IP address setting unit that sets in the second network device a second IP address that is different from the first IP address; an IP header editing unit that performs processing to make a destination of IP packets sent from the terminal via the third network an IP address of the second image processing apparatus; and a packet transmission unit that sends the IP packets processed by the IP header editing unit to a network via the first network device, and the second image processing apparatus includes a response header editing unit that performs processing to make the first network device the destination for responses to IP packets sent by the terminal via the first image processing apparatus.
