    To truly "connect" the 2 LAN's so that they can talk to one another, you *need* a Layer 3 device. There is no other option.

    You can use a Layer 3 swtich to accomplish this with a single piece of hardware, or you can use a physical router to connect the two.

    one could opt for using a cross over cable and forget the switch.

    IPHelper on a Cisco device might work but can't really overcome 2 different addressing schemes. Something has to route traffic if there is 2 different addressing schemes. As mjfera said, 2 different networks need a layer 3 device. there's no other way around it except the crossover direct connect.

    with no router, a switch or hub will not help you. sounds like a trick question. good luck.

    <<<<we will be given one NIC card aside on the on-board lan card...what will i do then?>>>>

    do you mean that you will dual-home the devices (workstations and servers, etc) so the onboard NIC is connected to one LAN and the second NIC is connected to the other?

    How many devices will you be doing this with?

    If this is the case, you'll simply plug one NIC into one LAN, assign it an IP address in that LAN, then do the same for the second NIC -

    If you're talkin about more than 1 or 2 devices dual homed I'd definitely recommend an L3 swithc like a Cisco 3560 or 3750, or at least an old Cisco 2621 with 2 fast ethernet interfaces and route between the lans - rahter than 2 NICs in the devices.

    You can use windows 2000 server or higher edition and enable routing and remore access to make two network talk to each other
