I think the problem is that your FreeBSD server is using 10.0.10.2 as
its own IP address but you have told DHCPd to use 10.0.10.1 to 10.0.10.6
as the range to give out to clients that request an IP. The 10.2 address
is part of this range. So you should change the range to be outside of
anything that you already have in use so that they don't conflict.
