I must be missing something here, because I can't get this to work for
some
reason. We are configuring DHCP in five offices (all one tree). We
have a
hardware VPN, and the offices subnets are as follows: Main office
10.10.10.x/23, remote office 1 10.10.12.x/24, remote 2 10.10.13.x/24,
remote
3 192.168.110.x/24, remote 4 192.168.111.x/24. I've created dhcp
servrers
for each office, and created the subnets. Each subnet object is
configured
with the mask specified above.

Then I go into other DHCP options and hit modify, for each subnet.
I'm
trying to specify a few settings for the client. I can add all
services no
problem except for one: subnet mask. For the main office, I specify
a mask
of /23 since that's the real mask. But the management console won't
accept
this. The error is "Mask range must be larger than the mask range
defined
in the subnet." For the subnet 10.10.10.x/23, it will accept a /22,
/21
etc, but it will not accept /23. 10.10.12.x/24 (and all the other /24

subnets), it will accept /23, /22, etc. In order for it to give out
the
right subnet, we have to "fudge" our subnets. We changed the subnet
10.10.10.x/23 to a /24, in order to be able to specify that it give
out /23.
Similarly, we would have to change our /24 subnets to /25 to give out
/24.
So either we're doing something wrong (we're missing something), or
something screwy is going on. I assume that we're missing something.
Is
that field for something else?
