Hmmm, maybe there is another problem in my config. I tried two requests within
ten seconds. Attached you'll find the debug. During the second request the
first ip-address is freed and can be used again. The lease-duration has the
standard value of 3600, so this can't be the reason.
This is the table radippool after the second request:

I'm afriad, but this won't work in my environment. I will need a different
subnetmask. Is it possible to use radgroupreply for this issue?
Thanks.
