When you change the DHCP server settings, the modem resets. Any devices that are connected to the
modem are disconnected when the modem resets and must obtain a new IP address when they reconnect
to the modem.
Disable the DHCP Server
You can disable the DHCP server only when the modem functions in Router mode
(see
Manage Router Mode and Bridge Mode
on page 22).
Note
If you do not need the modem to issue IP addresses to connected devices through its DHCP server, you
can disable the DHCP server.
To disable the modem’s DHCP server when the modem functions in Router mode:
1.
Launch a web browser from a device that is connected to the modem.
The device can be a computer that is directly connected to the modem or a client from a router that is
connected to the modem.
2.
In the address field of your browser, enter http://192.168.5.1.
The Dashboard page displays.
If you did not select the Remember me check box when you logged in previously, a
limited Dashboard page displays. In the Sign In field, enter the modem password
and click the Sign In button. The default password is password (case-sensitive).
Note
3.
Select Settings > Advanced > LAN.
The LAN page displays.
4.
Next to DHCP Server, select the Disable radio button.
The Submit button displays after you select the radio button.
By default, the Enable radio button is selected and the DHCP server issues IP addresses to connected
devices.
5.
Click the Submit button.
Your settings are saved.
Enable the DMZ
You can enable the DMZ settings only when the modem functions in Router mode
(see
Manage Router Mode and Bridge Mode
on page 22).
Note
In a demilitarized zone (DMZ) network configuration, a designated computer runs outside the firewall in the
DMZ. This computer intercepts incoming Internet traffic, providing an extra layer of protection for the rest
of the network, and sending all incoming data to a particular IP address.
