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 ...
Thanks.
