Description
Starting Local Address
Displays the starting address used by the built-in DHCP server
to distribute Private LAN IP addresses. In the example shown,
addresses between 2 and 9 can be used for devices on your
Private LAN that require fixed IP addresses such as printers or
a device assigned as a DMZ host.
Note:
The LAN IP address ending in 1 is reserved for the
internal gateway server. The LAN IP address ending in 255 is
also reserved and should not be used for CPE devices.
Number of CPEs
Enter the maximum number of devices allowed to connect to
the Private LAN.
Notes:
The Factory Default is 245. The maximum number of
devices is 253. This is the combined total of addresses
reserved for static IP addresses, for example, the sum of the
IP addresses between 2 and the value entered in the Starting
Local Address field and the value entered in the Number of
CPEs field.
The sum of the value entered in the Starting Local Address
field and the value entered in the Number of CPEs field
must always be 255 or less.
