Enable IGMP Snooping:
IGMP Snooping is the process of listening to IGMP (Internet Group
Management Protocol) network traffic. The feature prevents hosts on a local network from
receiving traffic for a multicast group they have not explicitly joined. It is enabled by default.
Enable Second IP:
You can configure the modem router’s second IP Address and Subnet
Mask for LAN Interface through which you can also access to the Web-based Utility as the
default IP Address and Subnet Mask.
DHCP Server:
The DHCP (Dynamic Host Configuration Protocol) server is enabled by default.
DHCP service will supply IP settings to computers connected to the modem router though the
Ethernet port which are configured to automatically obtain IP settings. When the modem
router is set for DHCP, it becomes the default gateway for DHCP client connected to it. If you
change the IP address of the modem router, you must change the range of IP addresses in
the pool used for DHCP on the LAN.
•
Start IP Address:
Enter a value for the DHCP server to start with when issuing IP
addresses. The default Start IP Address is
192.168.1.100
, and the Start IP Address must
be 192.168.1.100 or greater, but smaller than 192.168.1.254.
•
End IP Address:
Enter a value for the DHCP server to end with when issuing IP
addresses. The End IP Address must be smaller than 192.168.1.254. The default End IP
Address is
192.168.1.254
.
•
Leased Time:
The Leased Time is duration in which a DHCP client can lease its current
dynamic IP address assigned by the modem router. After the dynamic IP address has
expired, the user will be automatically assigned to a new dynamic IP address. The default
is
1440
minutes.
The detailed configuration about DHCP server, please refer to section
4.6 DHCP Server
.

Leased Time:
The Leased Time is the duration in which a DHCP client can lease its
current dynamic IPv6 address assigned by the modem router. After the dynamic IPv6
address has expired, the user will be automatically assigned a new dynamic IPv6
address. The default is 86400 seconds.
