    OK my dumb teacher threw a major curve ball at me today:

    The local LAN has been assigned an IP network Address of

    Each subnet of the above network needs to accomdate 300 host addresses.
    User the 3rd usable subnet for the LAN. Do not use subnet zero as the first subnet.

    I figured that the address using VLSM is /23 but when i try to enter that into Packet Tracers router interface an error pops up sying this cant be done with that subnet mask. Anybody get a different answer.
