I think the problem is that your FreeBSD server is using as 
its own IP address but you have told DHCPd to use to 
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.
