Specify Dhcp Server Settings; Address Reservation - NETGEAR N300 User Manual

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 a DHCP Server check box is selected.
3. Specify the range of IP addresses.
For example, using the default addressing scheme, define a range between 192.168.0.2
and 192.168.0.254, although you might want to save part of the range for devices with
fixed addresses.
• In the Starting IP Address field, specify the start of the range for the pool of IP
addresses in the same subnet as the modem router.
• In the Ending IP Address field, specify the end of the range for the pool of IP
addresses in the same subnet as the modem router.
4. Click Apply.
Your changes are saved.

To disable the DHCP Server feature in the modem router:
1. Select Advanced > LAN Setup.
2. Clear the Use Router as DHCP Server check box
3. Click Apply.
4. If no DHCP server is on your network, set your computers' IP addresses manually so that
they can access the modem router.

Address Reservation

When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the modem router's DHCP server.
Reserved IP addresses should be assigned to computers or servers that require permanent
IP settings.

To reserve an IP address:
1. Select Advanced > Setup > LAN Setup.
2. In the Address Reservation section of the screen, click the Add button.
3. In the IP Address field, type the IP address to assign to the computer or server.
Choose an IP address from the modem router's LAN subnet, such as 192.168.0.x.
4. Type the MAC address of the computer or server.
