DHCP client will usually re-submit a request. DHCP Lease Time must be
greater than 10 seconds (seconds must be between 0 and 59; minutes must
be between 0 and 59; and hours must be between 0 and 23). By default,
the DHCP Lease Time is set to 01:00:00:00.

13.3.4 Public LAN
The following screen will appear if you select Advanced > LAN > Public LAN from the main menu. This screen
contains the settings for determining how your modem will interact with the local devices connected to it. It is
recommended that these settings not be changed. This feature is mutually exclusive with the VLAN feature. If you
change the settings in this screen, click apply and then OK. If you click reset or Cancel, the screen will return to its
previous settings.
Public LAN allows the modem to issue DHCP addresses from its Public LAN IP address pool. IP addresses served
from the Public LAN pool bypass the NAT interface and are accessible from the WAN, allowing your computer to
have global address ability. To use the Public LAN feature, your ISP must support Multiple IP Address Passthrough.
NOTE:
1. By enabling the DHCP server for Public LAN, you automatically disable the DHCP Server for Private LAN. By
default, the modem’s Public LAN DHCP server is disabled, and the Private LAN DHCP server is enabled.
Whenever the Public LAN DHCP server is disabled, the modem will not issue public LAN IP addresses to
devices on your network.
2. Public LAN IP addresses are provided by your ISP. If you have questions about this feature, contact your ISP for
details.
3. By default, the Public LAN DHCP server is disabled. It is recommended that these settings not be changed unless
you are instructed to do so by your ISP.
