Note: If the IP Address or subnet mask for a LAN interface is changed, the

corresponding DHCP scope is created or modified for the interface.

This operation also involves setting default values for some

parameters. By default, Enterprise Edge sets the IP Address of

corresponding LAN interface to DNS Server, WINS Server, Default

Gateway options of the scope. It also sets the lease time to 3 days,

creates a range of addresses for the scope. If the IP Address of the

LAN interface is in the lower half of the subnet, the address range set

for the scope includes all the address above the LAN interface address.

If the IP Address of the LAN interface is in the upper half of the

subnet, the address range set for the scope includes all the address

below the LAN interface address. By default, the scope is enabled.
