Maybe this will help.  Here's part of my dhcpd.conf file showing a pool 
that gives out addresses on an overlaid private network:

   # private subnet / trusted devices
   subnet 192.168.107.0 netmask 255.255.255.0 {
     pool {
       range 192.168.107.20 192.168.107.252;
       option routers 192.168.107.1;    # NAT interface
       allow members of "trustednat";
       default-lease-time 900;
       max-lease-time 900;
       authoritative;
     }
   }

Then I configure a virtual network interface for that network, in 
/etc/sysconfig/network-scripts/ifcfg-eth0:192 :

DEVICE=eth0:192
BOOTPROTO=none
BROADCAST=192.168.107.255
IPADDR=192.168.107.254
NETMASK=255.255.255.0
NETWORK=192.168.107.0
TYPE=Ethernet
USERCTL=no
HWADDR=00:15:17:85:7b:ab
ONBOOT=yes

If the alias interface is up when dhcpd starts, everything just seems to 
work.  Can you give more details on how your setup is not working?
