The statement "allow unknown clients" implicitly denies everybody else,
your known clients. I know that in ancient versions of the server, a host
entry with a fixed address only made the client "known" on the subnet that
matched that IP. As mentioned earlier you had to define an ethernet address
twice, once with a fixed address and once without, to allow it to be known
on other subnets. I had the impression this is no longer true but I confess
that I have not tested it in years.
Try removing the "allow unknown clients" statement. If a defined host
has a fixed address this will be given in preference to a pool address so it
should not be necessary as far as I can see.
