    hi again i have questions about inbound or outbound
    (i mean placements)


    first : [​IMG]

    answer for this is outbound and eo interface of lab b router
    but

    i think if we put it to out even except accounting , we can't reach
    server am i wrong?(packet begins from accounting and passes
    lab b then if we put it outbound we can't reach server
    but also we can reach from nowhere to server)


    second :[​IMG]

    answer for this is outbound for s0 of router and it seems
    true none of them reaches internet and from them no packets
    go to internet

    but even if we put it inbound in my opinion it will be true
    since for out they can't reach internet , for in
    packets go internet but can't return for host access
    am i thinking wrong?(for inbound : from internet there will no packets
    return)

    third : i couldn't upload now

    later

    That's a bit weird. The highlighted paragraph above the second diagram appears to be saying something about restricting telnet access on a standard ACL. What's going on ? Am I missing something ?

    Well I looked at a similar lab some time ago....

    I think outbound on S0 as this will stop an internet session from starting up for all LAN segments.

    Though the specifics of the question indicate that you have to specify addresses and address ranges to adequately define the acl.

    Hint: map out all four address ranges, the subnet masks and the broadcast addresses...noting the VLSMs etc etc
