4. To get started, click on DHCP Options and then chose Scope from the
pull down menu.
5. Once the Create Scope (Local) window opens (see below), you will be
required to input a range of IP addresses in the IP Address Pool.
There is also an Exclusion Range used to prevent the DHCP server
from issuing addresses to existing devices that have already been
assigned IP addresses from this range. By using the Add and Remove
buttons, several different ranges can be excluded, and later included.
6. Another item that must be attended to is the Subnet Mask. This is a
number that is combined with a device’s IP address to determine which
subnet the device belongs to. For a Class C address you should input
255.255.255.0, and for Class B addresses use 255.255.0.0.
7. Make sure the Unlimited option under Lease Duration is checked.
This prevents the system from automatically disconnecting devices
that are using IP addresses in the specified range.
8. Assign a name to the scope, and if you would like, include a comment.
Click OK to accept the values.

Click on Yes to activate.

exclusively for use by your EDG-4508/4516 .
10.From the DHCP Manager - (Local) menu bar, click on Scope, and then
select Add Reservations.

IP address, Unique Identifier, Client Name, and Client Comment. First
enter the selected IP address, and then locate and enter your EDG-
4508/4516 ’s MAC address in the Unique Identifier field. (The MAC
address is located on EDG-4508/4516 ’s back panel.)
Be sure to enter the same Client Name that was entered in the Name
field of the Create Scope - (Local) window (see step 8 above). The
Client Comment is optional. At this point you should double-check
