Associate the IP pools with the respective IP binds.

[Settings]
AssociateBindsToPools=1  ; Default : 0

If the DHCP Server is configured to use more than one NIC with a separate subnet each (see Example 3 in the overview) then this entry associates the IPPOOL_x with the IPBIND_x. The two entries with the same number “x” belong together. Clients on subnet IPBIND_x get IP addresses assigned only from the pool defined by IPPOOL_x.
The default behavior (AssociateBindsToPools=0) is to view all IPPOOL_x as one big pool of IP addresses which can be assigned to any client regardless of the subnet IPBIND_x.
