    i have some questions regarding an ipsec tunnel
    which i want to setup between to hosts (A, B),

    but I want A and B to be in the same subnet.
    what are the possiblilities?

    also, i might meet the following situation:
    A <==> ipsec_gw <==> routers <==> ipsec_gw <===> B

    A <==> ipsec_gw <==> Layer-2(switches) <==> ipsec_gw <===> B

    can anyone give me a clue on the 2 stiuations?

    in (a), i just want an ip sec tunnel, but the endpoint hosts
    being in the same subnet.

    in (b), same situation but i don't have routing between the
    ipsec boxes, only switching.
    can i tweak some bridging and netgraph setup for that?

    thank you very much.
