  1. For the setup to work, the 16 IPs below must be identified as
    "interesting" for VPN encryption and these IPs can be identified via per
    host or subnet.

    If it's to be identified via host, they have to use /32 for the prefix
    length i.e 10.55.32.80/32 --- this is the same as 10.55.32.80 mask
    255.255.255.255. Using this method, you have to configure all 16 IPs, one
    by one.

    If it's to be identified via subnet, you have the choice of prefix length
    as long as long as all the 16 IPs are covered i.e 10.55.32.0/24
    (10.55.32.0 mask 255.255.255.0), 10.55.32.0/25 (10.55.32.0 mask
    255.255.255.128), etc...
    The benefit in using a subnet is you only have to define 1 subnet instead
    of defining all the 16 host IPs. But, caution has to be taken in order not
    to overlap w/ any existing IPs in use or possible concern of wasting
    allocated IPs.
    All IPs are assigned to PCs with WIndows OS

    This is the Q that my colleague send to me....the fact is my forgot how the colculation. Could anyone pls help me.

    Uhm.. What is the question? The above look like and answer to me :)

    And if this is some homework, then just forget it - school is for learning stuff yourself.
