N600 Wireless Dual Band Gigabit VDSL2 Modem Router DGND3800B
LAN Setup Screen Settings
The following settings are available.
Device Name. By default, this is DGND3800B (the modem router model). You can change it
to another name if you prefer.
LAN TCP/IP Setup
• Device Name. This is an abbreviated name of the modem router.
• Use Auto IP. Select this check box if you want the modem router to set up the LAN IP
addresses automatically.
• IP Address. The LAN IP address of the modem router.
• IP Subnet Mask. The LAN subnet mask of the modem router. Combined with the IP
address, the IP subnet mask allows a device to know which other addresses are local to
it, and which addresses have to be reached through a gateway or modem router.
Use Router as DHCP Server
Usually, this check box is selected so that the modem router functions as a Dynamic Host
Configuration Protocol (DHCP) server. For more information, see
Specify DHCP Server
Settings on page 51.
• Starting IP Address. Specify the start of the range for the pool of IP addresses in the
same subnet as the modem router.
• Ending IP Address. Specify the end of the range for the pool of IP addresses in the
same subnet as the modem router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer receives
the same IP address each time it accesses the modem router’s DHCP server. Assign
reserved IP addresses to servers that require permanent IP settings. For more information,
see
Address Reservation on page 52.
Specify DHCP Server Settings
By default, the modem router is set up as a DHCP server. You can specify the range of
addresses that the modem router assigns. You can also use another device on your network
as the DHCP server, or specify the network settings of all of your computers.
To specify the pool of IP addresses that the modem router assigns:
1. Select ADVANCED > LAN Setup.
2. Make sure that the Use Router as DHCP Server check box is selected.
3. Specify the range of IP addresses.
