Please log in for more thread options That is by design. To do what you want you would have to create the
reservation within the a scope that possibly could be created for only that
purpose - creating reservations and using all the IPs in the small scope for
reservations or temporarily creating exclusions for the IPs in the scope
that are not to be used so that legitimate computers do not get an IP from
that scope and then specify bogus default gateway/DNS/wins for that scope in
options to limit what the user can do with that IP lease such as no internet
access.
