

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

.

•

Start IPv6 Address:

Enter a value for the DHCPv6 server to start with when issuing IPv6

addresses.

•

End IPv6 Address:

Enter a value for the DHCPv6 server to end with when issuing IPv6

addresses.

•

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.



Site Prefix Configuration Type:

Select a type to assign prefix to IPv6 addresses. Delegated

and Static are provided.

1)

If Delegated is selected, please complete the following parameters.
