LAN

You can configure the DSL Router IP address
and Subnet Mask for the LAN interface.
If you will be multicasting (e.g. video streaming)
you can enable IGMP snooping. IGMP snooping
allows the router to efficiently determine where
the multicast traffic came from and where
it is headed. There are two IGMP snooping
options: standard or blocking mode.
If you want the DHCP server to automatically
assign IP addresses, select enable DHCP
server and enter the range of IP addresses that
the DHCP server can assign. Select Disable
DHCP server if you would like to manually
assign IP addresses.
The Save button only saves the LAN
configuration data, but does not apply the
configuration. Select the Save/Reboot button
to save the LAN configuration data, reboot the
router and apply the new configuration.
