    Ok, that helps to clarify my situation.

    I've worked around the problem by making a lot of the dhcp stuff
    fixed addresses, left a couple floating, dhcp can assign them
    whatever it has available. That leaves  only six addresses to be
    assigned for mac numbers by dhcp. And when some of the other users
    return from vacation I may be able to change some of them to fixed
    addresses also.

    I still have some control over access via the device mac addresses.
    That give me a means of controlling what the grandsons can do with
    their PS3 game boxes, etc.. I don't want them playing games on line
    for fear of exceeding my bandwidth allotment. They ask me when they
    want to do an update, etc. .

    Dhcp just makes it easier when I am dealing with Apple Mac and
    Windows devices where I am always muddling through an unfamiliar
    setup procedure. Fedora Linux makes it so simple I am spoiled ...
